Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Please refer to Figures 1 to 5 , Figure 1 A schematic diagram of the three-dimensional structure of a bottom plate pressing mechanism for an equipment cabin provided in a specific embodiment of the present invention; Figure 2 A schematic structural diagram of an equipment cabin bottom plate pressing mechanism provided in a specific embodiment of the present invention pressing the equipment cabin bottom plate against a support member; Figure 3 A schematic structural diagram of an equipment cabin bottom plate pressing mechanism provided by a specific embodiment of the present invention when the equipment cabin bottom plate is not pressed; Figure 4 for Figure 2 A magnified view of area A; Figure 5 for Figure 2 Magnified view of area B in FIG.

[0043] An embodiment of the present invention provides an equipment cabin bottom plate clamping mechanism, which is used to press the equipment cabin bottom plate 100 onto a support member, wherein the equipment cabin bottom plate clamping mechanism includes: a mounting seat 10 and a clamping member 20, the clamping member 20 includes a connecting portion 21, a toggle portion 22 and a clamping portion 23, the connecting portion 21 is rotatably connected to the mounting seat 10, the toggle portion 22 and the clamping portion 23 are arranged on the connecting portion 21, and in a natural state, the position of the lowest end of the toggle portion 22 is lower than the height position of the lowest end of the clamping portion 23, and the height position of the lowest end of the clamping portion 23 is higher than the height of the upper surface of the equipment cabin bottom plate 100. During installation, the equipment compartment bottom plate 100 can be pushed to move on the support. After the equipment compartment bottom plate 100 passes under the pressing portion 23, it will contact the toggle portion 22. As the equipment compartment bottom plate 100 continues to advance, it will push the toggle portion 22 to rotate, thereby driving the connecting portion 21 to rotate relative to the mounting seat 10. At the same time, the pressing portion 23 rotates toward the equipment compartment bottom plate 100. Finally, the pressing portion 23 will press the equipment compartment bottom plate 100 onto the support. When the equipment compartment needs to be opened, The equipment compartment bottom plate can be pulled in the reverse direction. Under the action of the pulling force, the pressing portion 23 will separate from the equipment compartment bottom plate 100, thereby releasing the pressing effect of the pressing portion 23. Therefore, the equipment compartment bottom plate 100 can be automatically pressed under the action of the pressing member 20 after being pushed in, and the pressing member 20 can be automatically released after being pulled out. Therefore, there is no need to manually operate the pressing member 20, thereby improving the convenience of operation and reducing labor intensity. In addition, it can also improve the efficiency of disassembly and assembly of the equipment compartment bottom plate 100. In addition, the pressing portion 23 of the pressing member 20 is rigidly pressed against the equipment compartment bottom plate 100, which can improve the stability of pressing the equipment compartment bottom plate 100 on the support, prevent the vehicle body from loosening under the action of vibration, and improve the installation stability of the equipment compartment bottom plate 100.

[0044] In some embodiments, as Figure 1As shown, the equipment compartment bottom plate clamping mechanism also includes an elastic member, which is respectively connected to the mounting seat 10 and the clamping member 20. In a natural state, the toggle portion 22 is in a vertical state, and the clamping portion 23 is in an inclined state relative to the toggle portion 22. The vertical state of the toggle portion 22 can be maintained by the elastic member, or the toggle portion 22 can be naturally in a vertical state under the action of gravity. For example, a counterweight portion that can balance the clamping portion 23 can be provided on the side of the toggle portion 22 away from the clamping portion 23. Based on this, the structure of the counterweight portion and the clamping portion 23 can be made the same, and they are symmetrically arranged relative to the toggle portion 22. When the equipment compartment bottom plate 100 passes under the counterweight portion from another direction and pushes the toggle portion 22 to rotate, the counterweight portion can rotate toward the equipment compartment bottom plate 100 and press the equipment compartment bottom plate 100 on the support member. When the equipment compartment needs to be opened, the equipment compartment bottom plate 100 can be pulled. When the equipment compartment bottom plate 100 is moved out from under the clamping part 23, the elastic part can push the clamping part 20 to reset under its elastic force, so that when the equipment compartment bottom plate 100 is pushed in again, the clamping effect can be automatically achieved.

[0045] In some embodiments, in order to improve the clamping stability of the clamping portion 23, a clamping surface is provided on the end of the clamping portion 23 away from the connecting portion 21, and the clamping portion 23 can be in surface contact with the equipment compartment bottom plate 100 through the clamping surface. Furthermore, a wear-resistant layer is provided on the side of the clamping portion 23 facing the equipment compartment bottom plate 100. The wear-resistant layer can be a concave-convex structure provided on the lower surface of the clamping portion 23, for example, a knurled layer, multiple pits or multiple protrusions are processed on the lower surface of the clamping portion 23. The concave-convex structure can increase the friction with the equipment compartment bottom plate 100, thereby ensuring the clamping effect of the clamping portion 23 on the equipment compartment bottom plate 100; or the wear-resistant layer is a rubber pad provided on the lower surface of the clamping portion 23, and the rubber pad can be installed on the lower surface of the clamping portion 23 in a detachable connection manner, for example, by screwing the rubber pad. The pad is connected to the pressing part 23, or the rubber pad is bonded to the pressing part 23, or the rubber pad is clamped to the pressing part 23. For example, a mounting groove can be provided at the bottom of the mounting part, and the extension direction of the mounting groove is parallel to the rotation axis of the pressing part 20. The mounting groove can be a constricted groove, such as a T-slot or a dovetail groove. The rubber pad is provided with a connecting protrusion that is mutually compatible with the constricted groove. During installation, the connecting protrusion can be inserted from one end of the constricted groove. When the rubber pad is worn, the rubber pad can be removed and replaced without replacing the entire pressing part 20, thereby reducing maintenance costs. In addition, the rubber pad can also prevent the pressing part 23 from scratching the equipment compartment bottom plate 100, and can also produce a certain amount of elastic deformation, which is conducive to improving the pressing stability of the pressing part 23 on the equipment compartment bottom plate 100.

[0046] In some embodiments, as Figure 3 and Figure 4As shown, a pressure block 231 is provided on the end of the clamping portion 23 away from the connecting portion 21, wherein the pressure block 231 can improve the clamping stability of the equipment compartment bottom plate 100, and the pressure block 231 extends in the direction away from the toggle portion 22, and the lower surface of the pressure block 231 is a clamping surface, wherein the intersection of the clamping surface and the side of the pressure block 231 facing the toggle portion 22 is transitioned by an arc. When the equipment compartment bottom plate 100 pushes the toggle portion 22 to rotate, the side of the bottom of the pressure block 231 facing the toggle portion 22 will first contact the equipment compartment bottom plate 100, and then as the clamping portion 23 gradually rotates, the clamping surface will be completely pressed on the equipment compartment bottom plate 100. Therefore, the above-mentioned arc transition structure can effectively reduce the wear of the pressure block 231 on the equipment compartment bottom plate 100, thereby effectively improving the service life of the equipment compartment bottom plate 100.

[0047] In some embodiments, please refer to Figure 1 The connecting portion 21, the toggle portion 22 and the pressing portion 23 are an integrally formed structure. The integrally formed structure can facilitate the assembly of the pressing member 20 on the mounting seat 10. The toggle portion 22 extends from the side of the connecting portion 21 along a first direction, and the pressing portion 23 extends from the side of the connecting portion 21 along a second direction. The first direction and the second direction are perpendicular to the rotation axis of the connecting portion 21. A preset angle is provided between the first direction and the second direction, that is, the connecting portion 21, the toggle portion 22 and the pressing portion 23 are in a herringbone structure. Among them, the intersection of the toggle part 22 toward the side of the pressing part 23 and the pressing part 23 toward the side of the toggle part 22 is an arc transition. When the pressing part 23 presses the equipment compartment bottom plate 100, the toggle part 22 is pushed by the equipment compartment bottom plate 100, and the pressing part 23 is supported by the equipment compartment bottom plate 100. There is a certain angle between the two forces. The greater the thrust, the greater the pulling force between the toggle part 22 and the pressing part 23. Therefore, the structural stability between the toggle part 22 and the pressing part 23 can be guaranteed through the arc transition structure.

[0048] In some embodiments, the elastic member is a torsion spring 30, and the connecting portion 21 is connected to the mounting base 10 via a rotating shaft 40, wherein the mounting base 10 and the connecting portion 21 are provided with mounting holes for connecting the rotating shaft 40, the rotating shaft 40 can be fixedly connected to the mounting base 10, and the mounting base 10 is rotatably connected to the rotating shaft 40, and the torsion spring 30 is sleeved on the rotating shaft 40, one end of the torsion spring 30 is connected to the mounting base 10, and the other end is connected to the pressing member 20. For example Figure 3 As shown, one end of the torsion spring 30 is connected to the side of the toggle portion 22 away from the pressing portion 23. In the natural state, the pressing member 20 is in a vertical downward state under the torsion force of the torsion spring 30. Figure 4As shown, when the equipment compartment bottom plate 100 moves to the right and pushes the toggle portion 22 to rotate to the right, the torsion spring 30 is in a contracted state. When the equipment compartment bottom plate 100 moves to the left, the toggle portion 22 rotates to the left due to the torsion force of the torsion spring 30. Under the torsion force of the torsion spring 30, the equipment compartment bottom plate 100 can be easily pulled out of the equipment compartment.

[0049] In some embodiments, as Figure 1 As shown, the mounting base 10 includes a connecting plate 11 and ears 12 provided at both ends of the connecting plate 11. The two ears 12 extend downward, that is, the cross-section of the mounting base 10 along the vertical direction is n-shaped, wherein the width of the two ears 12 gradually decreases from top to bottom, and the two ends of the rotating shaft 40 are connected to the ears 12. For example, the rotating shaft 40 can be a bolt. One end of the bolt can pass through one ear 12 and be fixed to the other ear 12. The end of the bolt can pass through the outer end surface of the ear 12 so that the bolt can be locked on the ear 12 by a nut. A stopper 121 is provided on the inner side of one of the ears 12. The stopper 12 1 can be integrally formed on the inner side of the support ear 12, or can be fixed in the support ear 12 by means of a threaded structure or welding. A limiting protrusion is provided on the connecting portion 21, and the limiting protrusion can be integrally formed on the connecting portion 21. When the equipment compartment bottom plate 100 is moved out from under the pressing portion 23, the torsion spring 30 can drive the pressing member 20 to rotate under the action of its torsion force until the limiting protrusion contacts the stopper 121 and stops rotating, thereby maintaining the reset state, thereby facilitating the equipment compartment bottom plate 100 to be extended into the equipment compartment again, so that the toggle portion 22 is in a vertical state and the pressing portion 23 is in a raised state.

[0050] In some embodiments, the connecting portion 21 is provided with an escape portion for accommodating the torsion spring 30, for example Figure 1 As shown, a groove forming the above-mentioned avoidance portion is provided in the middle of the connecting portion 21 to separate the connecting portion 21 into two parts. The torsion spring 30 can be wound around the section corresponding to the groove on the rotating shaft 40. One end of the torsion spring 30 extends out of the groove and is connected to the stopper 121, and the other end is fixedly connected to the connecting portion 21. When the equipment compartment bottom plate 100 pushes the toggle portion 22, the torsion spring 30 contracts. When the equipment compartment bottom plate 100 is pulled out, the toggle portion 22 will rotate in the opposite direction under the action of the torsion force of the torsion spring 30, so that the limiting protrusion contacts the stopper 121. At this time, the toggle portion 22 is in a vertical state. In addition to setting the torsion spring 30 in the avoidance portion, a torsion spring 30 can also be set at both ends of the rotating shaft 40, and a stopper 121 is provided on the inner side surfaces of the two support ears 12 respectively. Correspondingly, two limiting protrusions are also provided on the connecting portion 21, wherein gaps are respectively provided between the end surfaces of the connecting portion 21 and the two support ears 12, and this gap is used to accommodate the torsion spring 30. By arranging a torsion spring 30 at both ends of the connecting portion 21, the force balance of the clamping member 20 can be effectively improved.

[0051] An embodiment of the present invention further provides an equipment cabin, comprising an equipment cabin floor 100 and a support member, and further comprising the equipment cabin floor clamping mechanism provided in any of the above embodiments, wherein the support member is the bottom structure of the equipment cabin, and the equipment cabin floor 100 is connected to the support member of the equipment cabin by a pull-out method, thereby facilitating the user to open the bottom of the equipment cabin and thereby facilitate maintenance of the equipment within the equipment cabin. The beneficial effects of the equipment cabin can be referred to the equipment cabin floor clamping mechanism provided in the above embodiments, and will not be further described here.

[0052] In some embodiments, as Figure 2 As shown, the support member is a beam 200. Specifically, the equipment cabin includes two beams 200 arranged parallel to each other, and the inner sides of the two beams 200 are respectively provided with slide grooves. The two sides of the equipment cabin bottom plate 100 are slidably connected to the slide grooves, and the two beams 200 are respectively installed with equipment cabin bottom plate clamping mechanisms. The equipment cabin bottom plate clamping mechanisms are located above the slide grooves. Specifically, the bottom of the inner sides of the two beams 200 are respectively provided with a slide groove, and the extension direction of the slide groove is the length extension direction of the beam 200. The equipment cabin bottom plate clamping mechanism is installed at the upper part of the inner side of the beam 200. Both slide grooves can be selected as slide grooves with an L-shaped cross section. The clamping member 20 of the equipment cabin bottom plate clamping mechanism is located directly above the slide groove, wherein the beam 200 can be formed as one piece by bending the plate, and the slide groove is also The sliding groove structure formed by bending is equivalent to adding a bending structure on the beam 200, so it can enhance the structural strength of the beam 200. In addition, the L-shaped sliding groove structure is simple and easy to manufacture; or the two sliding grooves include an upper groove surface and a lower groove surface, and the width of the upper groove surface is smaller than the width of the lower groove surface, that is, the spacing between the lower groove surfaces of the two sliding grooves is smaller than the spacing between the upper groove surfaces of the two sliding grooves, wherein the difference between the upper groove surface and the lower groove surface is not less than the width of the clamping part 23 of the clamping member 20. During installation, both sides of the equipment cabin bottom plate 100 can be extended into the space between the upper groove surface and the lower groove surface. When the stop block 101 on the equipment cabin bottom plate 100 pushes the toggle part 22 to rotate, the clamping part 23 will follow the rotation, thereby pressing the equipment cabin bottom plate 100 on the lower groove surface. When the pressing portion 23 presses the equipment cabin bottom plate 100 against the lower groove surface, since the width of the lower groove surface is greater than the width of the pressing portion 23, the pressing stability of the equipment cabin bottom plate 100 can be improved. In addition, during the movement of the equipment cabin bottom plate 100, the equipment cabin bottom plate 100 is limited by the upper groove surface and the lower groove surface, which can guide the equipment cabin bottom plate 100, thereby avoiding the problem of misalignment of the equipment cabin bottom plate 100. In addition, the thickness of the two sides of the equipment cabin bottom plate 100 is less than the thickness of its body, that is, the side structure of the equipment cabin bottom plate 100 is a step structure, and the thinner areas on both sides of the equipment cabin bottom plate 100 are slidably connected in the slide groove, wherein the step structure can limit the equipment cabin bottom plate 100, which is conducive to ensuring the stability of the equipment cabin bottom plate 100 when it is pushed and pulled.

[0053] The bottom of the equipment cabin is provided with two cross beams 200 and a longitudinal beam, and the two ends of the longitudinal beam are connected to the two cross beams 200 respectively, and can be fixed by rivets, screws or welding. The equipment cabin bottom plate 100 can be a whole large bottom plate, or it can be a plurality of smaller bottom plates distributed along the length direction of the cross beam 200. For example, when the pull-out length of the equipment cabin bottom plate 100 is not restricted, that is, when the equipment cabin bottom plate 100 is fully pulled out of the equipment cabin without being blocked, a whole large bottom plate or a plurality of smaller bottom plates can be used; when the pull-out length of the equipment cabin bottom plate 100 is restricted, that is, when a whole bottom plate is pulled out of the equipment cabin bottom plate 100, it is restricted by other equipment and cannot be fully pulled out. At this time, Multiple bottom plates can be used, for example, two bottom plates can be selected, one of which can be inserted into the chute between the two beams 200 from one end of the bottom of the equipment cabin, and the other bottom plate can be inserted into the chute between the two beams 200 from the other end of the bottom of the equipment cabin. The two bottom plates can be moved in opposite directions to cover the bottom of the equipment cabin, and when the two bottom plates are moved in opposite directions, the bottom of the equipment cabin can be opened; or the two bottom plates can be moved in the same direction, for example, one of the bottom plates is first pushed into the chute between the two beams 200, and then the front end of the other bottom plate is pushed against the rear end of the bottom plate that has been pushed into the chute until the two bottom plates are pushed into the required position. At this time, the two bottom plates can realize the closure of the bottom of the equipment cabin. Whether to choose a whole bottom plate or multiple bottom plates can be selected according to actual needs.

[0054] To facilitate installation of the equipment compartment floor clamping mechanism on the crossbeam 200, an L-shaped connector can be used for connection. Specifically, the L-shaped connector includes a crossbeam and a vertical plate. The vertical plate can be bolted to the crossbeam 200, and the mounting base 10 can be bolted to the bottom of the crossbeam. Multiple bolts can be used to connect the vertical and crossbeams. Furthermore, waist-shaped holes can be provided on the vertical plates, allowing bolts to be inserted into the waist-shaped holes. The waist-shaped holes allow the vertical height of the vertical plates, and thus the height of the equipment compartment floor clamping mechanism, to be adjusted. This facilitates control over the installation of the equipment compartment floor clamping mechanism.

[0055] In order to improve the stability of the equipment cabin bottom plate 100 installed at the bottom of the equipment cabin, in this embodiment, a limiting portion 103 can be provided on the end of the equipment cabin bottom plate 100 away from the longitudinal beam. When the equipment cabin bottom plate 100 is pushed into the bottom of the equipment cabin, the limiting portion 103 contacts the end of the longitudinal beam 200 away from the longitudinal beam. At this time, the limiting portion 103 can be fixed to the beam 200 by the fastener 400. Figure 5As shown. When the equipment compartment bottom plate 100 needs to be pulled out, the fasteners 400 need to be removed first, and then the equipment compartment bottom plate 100 is pulled outward. The fasteners 400 can be bolts. In addition, a lock can be used to lock the limit portion 103 on the beam 200. Furthermore, a limit portion 103 can be provided at each end of the equipment compartment bottom plate 100 on the side away from the longitudinal beam, wherein the spacing between the two limit portions 103 is greater than the spacing between the two beams 200. During installation, the two limit portions 103 respectively contact the ends of the two beams 200, and can be connected by means of fasteners 400 or locks, so as to prevent the equipment compartment bottom plate 100 from automatically moving out from between the two beams 200, thereby ensuring the installation stability of the equipment compartment bottom plate 100. In order to facilitate pushing and pulling the equipment compartment bottom plate 100, a handrail can be provided at the tail end of the equipment compartment bottom plate 100, such as an n-shaped handrail or an L-shaped handrail.

[0056] In some embodiments, an equipment cabin bottom plate pressing mechanism is respectively provided at the middle position of the two cross beams 200. In addition, two elastic pressing mechanisms 300 can be respectively provided on the two cross beams 200. Figure 2 As shown, two elastic clamping mechanisms 300 are located on either side of the equipment compartment bottom plate clamping mechanism and are spaced apart along the longitudinal extension direction of the crossbeam 200. The elastic clamping mechanism 300 includes a support base and a rubber wheel. The structure of the support base can be the same as that of the connecting base of the equipment compartment bottom plate clamping mechanism. The rubber wheel can be mounted on the support base via a rotating shaft, and the bottom of the rubber wheel extends downward from the support base, wherein the rubber wheel is rotatable relative to the support base. Stop blocks 102 are provided on both sides of the upper surface of the equipment compartment bottom plate 100. The upper surface of the stop block 102 includes a front inclined surface and a rear flat surface. That is, the stop block 102 has a wedge-shaped structure. The distance between the rear flat surface and the upper surface of the equipment compartment bottom plate 100 is greater than the distance between the lowest end of the rubber wheel and the upper surface of the equipment compartment bottom plate 100, and the distance between the lowest end of the front inclined surface and the upper surface of the equipment compartment bottom plate 100 is less than the distance between the lowest end of the rubber wheel and the upper surface of the equipment compartment bottom plate 100, so that the front end of the stop block 102 can extend under the rubber wheel.

[0057] When installing the equipment compartment bottom plate 100, the equipment compartment bottom plate 100 is pushed to move, and the front inclined surface of the limit block 102 will first contact the rubber wheel. As the equipment compartment bottom plate 100 continues to move forward, the rubber wheel is forced to deform upward. When the rear plane of the equipment compartment bottom plate 100 contacts the rubber wheel, the advancement of the equipment compartment bottom plate 100 stops. At this time, the rubber wheel can press the equipment compartment bottom plate 100 against the crossbeam 200 under the pressure of its elastic deformation. In the process of pressing the equipment compartment bottom plate 100 by the rubber wheel, the pressing member 20 of the equipment compartment bottom plate pressing mechanism also presses the equipment compartment bottom plate 100, thereby realizing both rigid pressing and elastic pressing. There is a rigid clamping position and two elastic clamping positions on both sides of the equipment compartment bottom plate 100. Combined with the fasteners 400 at the two limiting parts 103 at the ends of the equipment compartment bottom plate 100, there are a total of eight fixed points on the equipment compartment bottom plate 100, four of which are elastic connections and four are rigid connections, which can effectively improve the installation stability of the equipment compartment bottom plate 100.

[0058] When disassembling the equipment compartment bottom plate 100, first remove the fastener 400 between the limit portion 103 of the equipment compartment bottom plate 100 and the crossbeam 200, then pull the equipment compartment bottom plate 100 outward. Under the action of the pulling force, the equipment compartment bottom plate 100 will move relative to the elastic pressing mechanism 300 and the equipment compartment bottom plate pressing mechanism. During the movement, the rubber wheel of the elastic pressing mechanism 300 will separate from the limit block 102, and at the same time, the pressing portion 23 of the pressing member 20 will separate from the equipment compartment bottom plate 100. Finally, pull the equipment compartment bottom plate 100 to the target position. Since the equipment compartment bottom plate 100 can be tightened or loosened by pushing or pulling the equipment compartment bottom plate 100 when installing or disassembling it, it is convenient for disassembling and assembling the equipment compartment bottom plate 100, thereby achieving the purpose of improving work efficiency.

[0059] In some embodiments, as Figure 2 As shown, a stopper 101 is provided on both sides of the upper surface of the equipment compartment bottom plate 100. The stopper 101 may be a rectangular parallelepiped structure and may be connected to the equipment compartment bottom plate 100 by screws or welded to the equipment compartment bottom plate 100. When installing the equipment compartment bottom plate 100, the user pushes the equipment compartment bottom plate 100. After the equipment compartment bottom plate 100 moves on the crossbeam 200 and the stopper 101 passes under the pressing portion 23, the stopper 101 pushes the toggle portion 22, and the pressing portion 23 rotates toward the equipment compartment bottom plate 100 and presses the equipment compartment bottom plate 100 against the stopper 101. The contact between the stopper 101 and the pressing portion 23 can reduce wear on the equipment compartment bottom plate 100, thereby ensuring the service life of the equipment compartment bottom plate 100.

[0060] In some embodiments, the equipment compartment bottom plate clamping mechanism and the elastic clamping mechanism 300 can both be installed on the crossbeam 200 via a detachable connection. Accordingly, the stopper 101 and the limit block 102 can also be detachably connected to the equipment compartment bottom plate 100, for example, by using screws to install the above parts. When the connection rigidity requirements for the equipment compartment bottom plate 100 are not high, the equipment compartment bottom plate clamping mechanism and the stopper 101 can be replaced with the elastic clamping mechanism 300 and the limit block 102; when the connection rigidity requirements for the equipment compartment bottom plate 100 are high, the elastic clamping mechanism 300 and the limit block 102 can be replaced with the equipment compartment bottom plate clamping mechanism and the stopper 101. In addition, after frequent pushing and pulling, if the equipment compartment bottom plate clamping mechanism and the elastic clamping mechanism 300, as well as the limit block 102 and the stopper 101, are worn, the severely worn parts can be replaced, and the other lightly worn parts can be retained, thereby achieving the purpose of reducing maintenance costs.

[0061] In some embodiments, as Figure 2As shown, the equipment cabin bottom plate 100 includes a first bottom plate and a second bottom plate, both sides of which can be slidably connected to the sliding groove of the crossbeam 200, and one end of the two crossbeams 200 is connected to a longitudinal beam. This longitudinal beam is used to reinforce the crossbeam 200 and also to limit the equipment cabin bottom plate 100. A first elastic clamping component is provided on one end of the two crossbeams 200 close to the longitudinal beam. The first elastic clamping component includes a first support and a first rubber wheel. The first rubber wheel is rotatably connected to the first support, and the first support is connected to the crossbeam 200. After the front end of the first bottom plate moves to contact with the first rubber wheel, as the first bottom plate continues to move forward, the first rubber wheel will elastically deform until the front end of the first bottom plate moves to contact the longitudinal beam and stops. At this time, the first rubber wheel is located above the first bottom plate. Under the elastic deformation of the first rubber wheel, the first bottom plate can be pressed against the crossbeam 200. A limit block 102 and a stop block 101 are respectively provided on both sides of the upper surface of the second bottom plate. The stop block 101 is arranged at a position on the upper surface of the second bottom plate close to the first bottom plate, and the limit block 102 is arranged at a position on the second bottom plate away from the first bottom plate. The equipment cabin bottom plate 100 clamping assembly is located in the middle position of the crossbeam 200, and a second elastic clamping assembly is provided on the crossbeam 200 away from the first bottom plate. The second elastic clamping assembly includes a second support and a second rubber wheel, which is rotatably connected to the second support. When the second bottom plate is pushed into the sliding groove of the two crossbeams 200, the front end of the second bottom plate will first pass through the bottom of the second rubber wheel until the front end of the second bottom plate contacts the rear end of the first bottom plate and stops moving. At this time, the clamping part 23 of the equipment cabin bottom plate 100 clamping assembly is pressed on the upper surface of the stop block 101, and the second rubber wheel is pressed on the limit block 102 under the action of its own elastic deformation. A limiting portion 103 can be set on the end of the second bottom plate away from the first bottom plate. After the limiting portion 103 contacts the end of the beam 200, the limiting portion 103 is fixed to the beam 200 by the fastener 400, thereby achieving the purpose of fixing the first bottom plate and the second bottom plate to the bottom of the equipment cabin.
