Description

Technical Field

[0001] The invention relates to the technical field of auxiliary installation of reducers, in particular to a main reducer installation structure of a mine-proof vehicle. Background Art

[0002] With the continuous development of new energy technology, various vehicles are beginning to be designed with new energy as the main drive. When designing new energy vehicles, due to the loss of structures such as the engine, clutch, and fuel tank, the bottom is usually a distribution design of the power supply, motor, and related temperature control system. In the design of new energy mine-proof vehicles, due to the lightning protection requirements of the bottom of the vehicle, combined with the design mode of new energy vehicles, the bottom plate will be designed to be non-flat, usually with a V-shaped or isosceles trapezoidal structure at the bottom. This leads to the need to adapt the structural form of the installation shell to the bottom plate when installing the main reducer.

[0003] The prior art generally adopts a workpiece bonding method, that is, an auxiliary part is directly bonded to the bottom plate, and the auxiliary part is then fixed to the mounting shell of the main reducer to complete the bottom fixation. Although this structure can ensure installation, due to the variety of bottom plate structural forms of new energy mine-proof vehicles, this method of using specific parts to adapt and fix requires a separate design for each shape of the bottom plate, which delays the overall research and development efficiency of the vehicle. Summary of the invention

[0004] The present invention aims at the deficiencies in the prior art and provides the following technical solutions:

[0005] The main reducer installation structure of a mine-proof vehicle comprises a shell and two sets of connecting arms.

[0006] Specifically, the two groups of connecting arms are respectively arranged on both sides of the shell, and the connecting arms include arm 1 and arm 2. One end of the arm 1 is connected to a mounting plate for connecting to a base plate by a rotating shaft, and the other end of the arm 1 is connected to the rotating shaft of arm 2, and the other end of the arm 2 is connected to the rotating shaft of the shell. A penetrating movable groove is provided on the surface of the arm 1 and the arm 2, and a positioning sleeve that moves along the movable groove is provided inside the movable groove. The positioning sleeve is in a vertical state, and a positioning shaft for limiting the rotation of the arm 1 and the arm 2 is fixed by a thread on the inner side of the two positioning sleeves.

[0007] As an improvement of the above technical solution, a plurality of limiting rings are integrally formed on the surface of one side of the mounting plate away from the base plate, a limiting shaft is arranged passing through the interior of the limiting ring, one end of the support arm one is arranged between two adjacent limiting rings, and the limiting shaft passes through the support arm one and is located at the end of the limiting ring.

[0008] As an improvement of the above technical solution, a connecting groove is formed at one end of the arm one and the arm two away from the mounting plate, one end of the arm two is arranged inside the connecting groove of the arm one, a rotating shaft is penetrated through one side of the connecting groove, a connecting plate is detachably fixed to one side of the shell, an ear plate is integrally formed on the end surface of the connecting plate away from the shell, the ear plate is arranged inside the connecting groove of the arm two, the rotating shaft inside the connecting groove of the arm one penetrates the arm two, and the rotating shaft inside the connecting groove of the arm two penetrates the ear plate.

[0009] As an improvement of the above technical solution, rectangular track grooves are opened on both side walls of the movable groove, positioning blocks are arranged inside the track grooves, side shaft sleeves are threadedly connected on both sides of the positioning sleeves, and the ends of the positioning blocks are integrally formed with round shafts inserted into the side shaft sleeves.

[0010] As an improvement to the above technical solution, the method of installing the side bushing and the positioning sleeve to the circular shaft relies on the following steps:

[0011] S11: Sleeve the side shaft sleeves on the outside of the circular shaft, and adjust the positions so that the two side shaft sleeves are on the same horizontal plane.

[0012] S12: Place the locating sleeve between the two side sleeves and screw the side sleeves until they are fully screwed into the side walls of the locating sleeves.

[0013] As an improvement of the above technical solution, a retractable positioning plate is provided on one end face of the shell close to the bottom plate, and a horizontally penetrating positioning groove is opened at one end of the positioning plate close to the positioning shaft, and the positioning shaft penetrates into the interior of the positioning groove.

[0014] As an improvement of the above technical solution, a limiting track is integrally formed on the upper end surface of the shell, the limiting track penetrates inside, the positioning plates are respectively inserted from both ends of the limiting track, and an elastic member is connected between the tails of the two positioning plates.

[0015] As an improvement of the above technical solution, positioning frames for connecting to the cross arm assembly are integrally formed at both side ends of the shell close to the connecting arm.

[0016] As an improvement of the above technical solution, the installation method of the main reducer installation structure includes the following steps:

[0017] S21: First, fix the two mounting plates to the base plate.

[0018] S22: Determine the height of the housing according to the positions of the cross arm assembly and the power shaft, and locate the housing by using a positioning component.

[0019] S23: Move the positioning sleeves in the first arm and the second arm to a vertical concentric state, and screw in the positioning shaft until the positioning shaft and the two positioning sleeves are fixed to complete the position fixation of the main reducer mounting structure.

[0020] Beneficial effects of the present invention:

[0021] By opening a penetrating movable groove between the first arm and the second arm, and combining a positioning sleeve that moves linearly in the movable groove, a restriction structure for the double-point positioning of the positioning shaft is formed. After completing the installation and adjustment, it is only necessary to move the positioning sleeve to a position where the positioning shaft can be installed. When the positioning shaft fixes the two positioning sleeves at the same time, the entire structure forms a three-point positioning around the position where the rotating shaft is connected, thereby ensuring the stability between the structural parts. In addition, since the first arm and the second arm are connected by a rotating shaft, they can adapt to installation operations in a larger range and can meet the installation requirements of new energy mine-proof vehicles.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] The prior art generally adopts a workpiece bonding method, that is, an auxiliary part is directly bonded to the bottom plate, and the auxiliary part is then fixed to the mounting shell of the main reducer to complete the bottom fixation. Although this structure can ensure installation, due to the variety of bottom plate structural forms of new energy mine-proof vehicles, this method of using specific parts to adapt and fix requires a separate design for each shape of the bottom plate, which delays the overall research and development efficiency of the vehicle.

[0032] To solve the above problems, see Figures 1 to 4 The main reducer installation structure of the mine-proof vehicle includes: a shell 10 and two sets of connecting arms 20.

[0033] Specifically, two groups of connecting arms 20 are respectively arranged on both sides of the shell 10, and the connecting arms 20 include a support arm 1 21 and a support arm 22. One end of the support arm 1 21 is connected to a mounting plate 201 for connecting to the base plate 30 through a rotating shaft, and the other end of the support arm 1 21 is connected to the support arm 2 22 rotating shaft, and the other end of the support arm 22 is connected to the shell 10 rotating shaft. A penetrating movable groove 221 is provided on the surface of the support arm 1 21 and the support arm 2 22, and a positioning sleeve 24 that moves along the movable groove 221 is provided inside the movable groove 221. The positioning sleeve 24 is in a vertical state, and the inner sides of the two positioning sleeves 24 are threadedly fixed with a positioning shaft 23 for limiting the rotation of the support arm 1 21 and the support arm 2 22.

[0034] That is, the connecting arm 20 whose angle and position can be adjusted is formed by the cooperation between the adjustable support arm 1 21 and the support arm 22. After the connection arm 20 is adjusted, it is positioned by the positioning shaft 23 arranged therein. Since the positioning sleeve 24 is in a linear moving state and the positioning sleeve 24 always needs to be in a vertical state, its opening is always facing the upper and lower ends. When the moving grooves 221 of the support arm 1 21 and the support arm 22 have overlapping parts when viewed from above, the movement of the positioning sleeve 24 can be limited by moving the positioning sleeve 24 to the overlapping position and then screwing in the positioning shaft 23. Since the connection state between the support arm 1 21 and the support arm 22 is a triangular connection, when there is no external force, the positioning sleeve 24 can only move linearly, and the opening of the positioning sleeve 24 is always facing the vertical state up and down, the positioning sleeve 24, the positioning shaft 23 and the connection between the support arm 1 21 and the support arm 22 form a stable triangular connection state, so that a stable fixed state can be formed after the angle adjustment of the connection arm 20 is completed.

[0035] In order to facilitate the fixing of the support arm 21 and the mounting plate 201, please refer to Figure 2 and Figure 3 A plurality of limiting rings 202 are integrally formed on the surface of one side of the mounting plate 201 away from the base plate 30, a limiting shaft 203 is provided inside the limiting ring 202, one end of the support arm 21 is provided between two adjacent limiting rings 202, and the limiting shaft 203 passes through the support arm 21 and is located at the end of the limiting ring 202.

[0036] That is, the support arm 21 is fixed by the same hinged method, and the mounting plate 201 is fixed by bolts penetrating the bottom plate 30. Figure 1 and Figure 3 As shown, after the positioning shaft 23 is fixed, the support arm 1 21 and the support arm 22 are in a stable state, so they can be approximately regarded as a rod body. After the adjustment and fixation, the connecting arms 20 on both sides can be approximately regarded as two rod bodies, and the two rod bodies are respectively fixed to the mounting plate 201 and the shell 10, forming a quadrilateral state. If it is not a quadrilateral in a rectangular state, there are still certain restrictions between the structural parts, and the overall structure is not easy to shake. However, if the formed quadrilateral state is a rectangle, it will cause structural instability, and if the operator tilts during positioning, that is, the angle of the positioning sleeve 24 that is screwed in first is not in a vertical state, then the subsequent positioning sleeve 24 in the support arm 1 21 will also be tilted at an angle. In this case, although the positioning shaft 23 has completed the fixation of each structural member, due to the tilt of the structure, the positioning shaft 23 may not be fully screwed in. In some cases, if the chassis design structure is compact, it may cause problems that cannot be installed normally.

[0037] Based on the above reasons, when the mounting plate 201 is installed by means of a rotating shaft connection, after the positioning shaft 23 is screwed in and fixed, it is also necessary to ensure that the entire connecting arm 20 and the structure connected thereto are in a stable fixed state.

[0038] On the basis of the above solution, in order to ensure that the entire connecting arm 20 and the structure connected thereto are in a stable fixed state, please refer to Figures 1 to 3 A retractable positioning plate 111 is provided on one end surface of the housing 10 close to the bottom plate 30 , and a horizontally penetrating positioning groove 112 is formed on one end of the positioning plate 111 close to the positioning shaft 23 , and the positioning shaft 23 penetrates into the interior of the positioning groove 112 .

[0039] That is, the insertion angle of the entire positioning shaft 23 is limited by the positioning plate 111. Since the positioning plate 111 can only move horizontally, as long as the positioning shaft 23 is inserted into the positioning plate 111, it can be ensured that the positioning shaft 23 is in a vertical state. In this case, the upper positioning sleeve 24 and the direction of the positioning shaft 23 can be adaptively adjusted.

[0040] Similarly, after the support arm 1 21 and the support arm 2 22 on both sides are approximated as a rod body, the positioning plate 111 is equivalent to adding an angle steering restriction to the rod body. Since the approximate rod body cannot be steered, a relatively stable quadrilateral structure is formed, thereby ensuring the stability of the overall structure.

[0041] In one embodiment, see Figures 1 to 3 The upper end surface of the housing 10 is integrally formed with a limiting track 11 , which penetrates the interior of the limiting track 11 , and positioning plates 111 are respectively inserted from both ends of the limiting track 11 , and an elastic member 113 is connected between the tails of the two positioning plates 111 .

[0042] The purpose of setting the elastic member 113 is to provide a recovery power structure. When disassembling, the positioning plate 111 can be automatically retracted through the restoring deformation force of the elastic member 113. When the positioning plate 111 is stretched, if the positioning shaft 23 is inserted, the positioning shaft 23 can be squeezed and clamped. There is no need for the operator to hold the control manually, which makes it convenient for the operator to perform single-person operation under the chassis.

[0043] In order to ensure the integrity of the solution, a detailed connection solution is further provided, as follows: Figures 1 to 7 As shown, a connecting groove 222 is provided at one end of the support arm 1 21 and the support arm 22 away from the mounting plate 201, one end of the support arm 22 is arranged inside the connecting groove 222 of the support arm 1 21, and a rotating shaft 223 is penetrated through one side of the connecting groove 222. A connecting plate 25 is detachably fixed to one side of the shell 10, and an ear plate 251 is integrally formed on the end surface of the connecting plate 25 away from the shell 10, and the ear plate 251 is arranged inside the connecting groove 222 of the support arm 22, the rotating shaft 223 inside the connecting groove 222 of the support arm 1 21 penetrates the support arm 22, and the rotating shaft 223 inside the connecting groove 222 of the support arm 22 penetrates the ear plate 251.

[0044] That is, a rotatable connection structure is formed by the connecting groove 222 and the rotating shaft 223, and the rotation direction is centered on the rotating shaft 223. The structural type of the support arm 21 and the support arm 2 22 is the same, but the overall size of the support arm 1 21 is slightly smaller than the support arm 2 22. This is to ensure that the support arm 2 22 can be installed inside the connecting groove 222 of the support arm 1 21.

[0045] In order to realize the linear movement of the positioning sleeve 24 and ensure that the positioning sleeve 24 is always in a vertical state no matter where it moves to, please refer to Figures 1 to 7 A rectangular track groove 2211 is formed on both side walls of the movable groove 221, a positioning block 2212 is arranged inside the track groove 2211, side shaft sleeves 241 are threadedly connected to both sides of the positioning sleeve 24, and a round shaft 2213 inserted into the side shaft sleeve 241 is integrally formed at the end of the positioning block 2212.

[0046] That is, a positioning block 2212 is set inside the track groove 2211, and the linear movement of the positioning sleeve 24 is limited by the positioning block 2212. On this basis, a side shaft sleeve 241 is set on the outside of the positioning sleeve 24, and the side shaft sleeve 241 is inserted into the round shaft 2213. This method can ensure that the side shaft sleeve 241 can be adjusted in angle. It only needs to adjust the angle of the side shaft sleeve 241 after the position adjustment is completed.

[0047] Based on the above solution, in order to facilitate the operator to disassemble and install, the following method is also provided to install the side sleeve 241, the positioning sleeve 24, and the round shaft 2213, which specifically includes the following steps:

[0048] S11: Sleeve the side sleeves 241 on the outside of the circular shaft 2213, and adjust the positions so that the two side sleeves 241 are on the same horizontal plane.

[0049] S12: Place the positioning sleeve 24 between the two side sleeves 241 , and screw the side sleeves 241 until the side sleeves 241 are completely screwed into the side walls of the positioning sleeve 24 .

[0050] The side sleeve 241 and the positioning sleeve 24 can be stably installed on the circular shaft 2213 by the above method. When disassembling, the side sleeve 241 is loosened and the positioning sleeve 24 is removed first.

[0051] In one embodiment, see Figure 1 and Figure 2 The housing 10 is integrally formed with a positioning frame 12 at both side ends close to the connecting arm 20 for connecting the cross arm assembly.

[0052] like Figure 2 As shown, a through slot is opened on the side thereof, and the slot is used to fix the cross arm assembly. At least four groups of slots are opened on both sides of the housing 10, and are used to connect the cross arm assemblies of the wheel sets on both sides.

[0053] In order to facilitate the installation of operators, the installation method of the main reducer installation structure is also provided, which specifically includes the following steps:

[0054] S21: First, fix the two mounting plates 201 to the bottom plate 30 .

[0055] S22: Determine the height of the housing 10 according to the positions of the cross arm assembly and the power shaft, and position the housing 10 using a positioning component.

[0056] S23: Move the positioning sleeves 24 in the support arm 1 21 and the support arm 22 to a vertical concentric state, and screw in the positioning shaft 23 until the positioning shaft 23 and the two positioning sleeves 24 are fixed to complete the position fixation of the main reducer mounting structure.

[0057] During the installation process of step S21, the positions of arm 1 21 and arm 2 22 will also deflect accordingly. Since the structures on both sides are symmetrical, they are still in a symmetrical state during the process of fixing the mounting plate 201. During the operation of step S22, it is necessary to adjust the position of the shell 10 according to the wheel group to ensure that in the subsequent installation process, the power shaft can be accurately inserted into the groove opened on the shell 10. After the height is determined, the shell 10 can be height-positioned by the positioning assembly. After the positioning is completed, the positions of arm 1 21 and arm 2 22 are fixed. At this time, the positions of the two positioning sleeves 24 can be adjusted. First, the bottom positioning sleeve 24 is fixed, that is, the positioning shaft 23 is tightened with the bottom positioning sleeve 24. After the fixation is completed, the positioning shaft 23 is restricted by the positioning plate 111. When the restriction is completed, the positioning shaft 23 is squeezed. At this time, the operator can loosen the positioning shaft 23 and adjust the upper positioning sleeve 24. After the position adjustment is completed, the positioning shaft 23 is screwed in again to complete the fixation of the bottom structure.

[0058] In step S22, the positioning assembly can be supported by a support member, such as a support plate. If the height is high, a retractable platform support can be used. When the positioning shaft 23 is not inserted, it is only necessary to limit the lowest position of the shell 10.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
