[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0035] Combine the following Figures 1 to 3 It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute any limitation to the present invention.

[0036] See also Figures 1 to 3 As an embodiment of the present invention, the present invention provides a vacuum pump fixing device for vacuum loading preloading of highway ramp roadbed, including a base plate 1, a supporting structure 2 and an anti-collision structure 3.

[0037] Among them, the support structure 2 is fixedly installed on the upper surface of the base plate 1, the vacuum pump body 6 is also fixed on the upper surface of the base plate 1, and the support structure 2 is arranged around the vacuum pump body 6 to protect the vacuum pump body 6 and avoid impact on the vacuum pump body 6 during construction.

[0038] The anti-collision structure 3 is connected to the supporting structure 2 and has two states: retracted and supported. It is used to support and protect the vacuum pump body 6 and increase the stability and safety of the fixed structure.

[0039] A base 4 and an anti-skid structure are provided on the other side of the bottom plate 1 and opposite to the supporting structure 2 , and both the base 4 and the anti-skid structure are in contact with the ground.

[0040] It can be understood that the present invention installs the vacuum pump body 6 on the bottom plate 1, and sets the support structure 2 around the vacuum pump body 6 on the bottom plate 1, which can effectively protect the vacuum pump body 6 and prevent the vacuum pump body 6 from being knocked down and causing the connecting pipe to be detached, affecting the construction efficiency. At the same time, by connecting the anti-collision structure 3 to the support structure 2, the anti-collision structure 3 has two states: retracted and supported. On the one hand, it can cooperate with the support structure 2 to play a good supporting role, and on the other hand, it can effectively buffer the impact, and at the same time, it is convenient to store and can reduce the floor space.

[0041] In this embodiment, the bottom plate 1 is rectangular or square, and there are four bases 4, which are respectively located at the four corners of the rectangular or square bottom plate 1, and are used to position and support the vacuum pump fixture as a whole.

[0042] In this embodiment, the support structure 2 includes a support plate 21 and a rotating shaft 22 rotatably connected between two adjacent support plates 21 .

[0043] The support structure 2 may be completely distributed around the vacuum pump body 6, that is, arranged around the vacuum pump body 6; Figure 2 As shown, they may also be arranged on both sides of the vacuum pump body 6 only along the length direction or width direction of the vacuum pump body 6 . The specific selection is determined according to actual usage and the connecting pipelines on the vacuum pump body 6 .

[0044] When the support structure 2 is located on both sides of the vacuum pump body 6, there are four support plates 21, which are respectively located at the four corners of the base plate 1 and can be welded or fixed to the base plate 1 by bolts. The rotating shaft 22 is connected to the two support plates 21 in parallel.

[0045] In this embodiment, specifically, the anti-collision structure 3 includes a driving component and an anti-collision component; wherein the driving component and the anti-collision component are both connected to the rotating shaft 22 .

[0046] More specifically, the anti-collision assembly includes an anti-collision rod 31 and a support block 32. The support block 32 is fixedly connected to one end of the anti-collision rod 31, and the other end of the anti-collision rod 31 is fixedly connected to the rotating shaft 22. The anti-collision rod 31 can be directly welded to the rotating shaft 22, and can also be installed on the rotating shaft 22 by a suitable fit.

[0047] In addition, the shape of the support block 32 may be spherical, and the material of the support block 32 may be rubber, which has a large friction coefficient, and thus has a large friction force, and can be stably supported on the ground.

[0048] The anti-collision structure 3 has two states: retracted and supported. When the anti-collision structure 3 is in the supported state, a right triangle is formed between the anti-collision rod 31 and the ground and the supporting structure 2. Since the triangle is stable, it can ensure that the vacuum pump body is supported by the anti-collision structure 3 on the basis of the supporting structure 2, and the stability is better.

[0049] When the anti-collision structure 3 is in the retracted state, the anti-collision rod 31 is located directly above the supporting structure 2, and the floor space of the vacuum pump fixing device is equivalent to the floor space of the bottom plate 1, and the floor space will not be increased due to the anti-collision structure 3. Therefore, the floor space can be effectively reduced, which is convenient for storage and movement.

[0050] In this embodiment, the driving assembly includes a stepper motor 33 and a worm gear structure, in which a worm wheel 34 is fixedly mounted on the rotating shaft 22 , and the worm wheel 34 can be fixed on the rotating shaft 22 by a key connection, and the worm gear 35 is connected to the output end of the stepper motor 33 .

[0051] The worm 35 is driven by the stepper motor 33 to rotate the worm wheel 34 meshing with the worm 35. The worm wheel 34 synchronously drives the rotating shaft 22 to rotate, and then the anti-collision rod 31 drives the supporting block 32 to rotate around the rotating shaft 22, thereby realizing the operation of the anti-collision structure 3 in the retracted state or the supporting state.

[0052] Specifically, the rotating shaft 22 drives the anti-collision rod 31 to rotate, and the anti-collision rod 31 drives the support block 32 to rotate synchronously, and the support block 32 rotates to the ground for support.

[0053] In this embodiment, the anti-slip structure is a plurality of anti-slip strips 5 arranged in an array on the bottom surface of the bottom plate 1, and the anti-slip strips 5 are parallel to the bottom plate 1. The anti-slip strips 5 can be arranged in an equidistant array along one side of the base 4, or can be arranged in other shapes, such as multiple layers of diamond-shaped convex strips diffused outward from the center of the bottom plate 1, and the multiple layers of diamond-shaped convex strips are arranged concentrically.

[0054] Among them, the anti-skid strip 5 is made of rubber material, and has a large friction coefficient, so the friction force is large and the anti-skid effect is better.

[0055] See also Figure 2 and Figure 3 As another embodiment of the present invention, based on the above embodiment, in order to prevent the anti-collision bar 31 from being damaged by excessive impact and affecting the vacuum pump body 6, the anti-collision bar 31 is divided into two sections, that is, the anti-collision bar 31 has a first anti-collision section 311 and a second anti-collision section 312, and a buffer component is provided between the first anti-collision section 311 and the second anti-collision section 312.

[0056] In this embodiment, the buffer assembly includes a connecting assembly and a spring assembly; wherein the spring assembly is symmetrically arranged on both sides of the connecting assembly and is arranged in parallel with the connecting assembly.

[0057] Specifically, the connecting assembly includes a connecting block 36 and a connecting seat 37. The connecting block 36 is located in the first anti-collision section 311, and the connecting seat 37 is located in the second anti-collision section 312. The connecting block 36 and the connecting seat 37 are rotatably connected, which is equivalent to the first anti-collision section 311 or the second anti-collision section 312 being able to rotate around the rotating connection point to adapt to various anti-collision situations.

[0058] There is a gap between the first anti-collision section 311 and the second anti-collision section 312 , so as to facilitate the overall bending or stretching of the anti-collision rod 31 .

[0059] The projection area of ​​the connecting block 36 is smaller than the projection area of ​​the first anti-collision section 311 , so as to facilitate the rotational connection with the connecting seat 37 .

[0060] Specifically, the spring assembly includes a first tension spring 38 and a second tension spring 39, and the first tension spring 38 and the second tension spring 39 are connected through a mounting block 310 fixed on the first anti-collision section 311 and the second anti-collision section 312. Two mounting blocks 310 are provided, and are respectively fixed at the ends of the first anti-collision section 311 and the second anti-collision section 312 close to each other.

[0061] Since both sides of the first anti-collision section 311 and the second anti-collision section 312 are provided with the first tension spring 38 and the second tension spring 39, when the first anti-collision section 311 and the second anti-collision section 312 are kept vertical without external force, it is equivalent to a complete anti-collision rod 31.

[0062] When the fixing device is hit, one of the first tension spring 38 and the second tension spring 39 is stretched, and the first anti-collision section 311 and the second anti-collision section 312 rotate relative to each other; when the impact disappears, the stretched tension spring is reset, thereby driving the first anti-collision section 311 and the second anti-collision section 312 to reset. This process can effectively buffer and prevent the fixing device from being damaged by impact.

[0063] During the working process of the present invention, the vacuum pump body 6 is placed at the construction site, the base 4 is positioned, and the anti-slip strip 5 contacts the ground to limit the movement of the bottom plate 1. The stepper motor 33 works in forward rotation, driving the worm 35 to rotate, the worm 35 meshes and drives the worm wheel 34 to rotate, the worm wheel 34 drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the anti-collision rod 31 and the support block 32 to rotate, the support block 32 rotates to the ground, contacts the ground for support, and can strengthen the support of the vacuum pump body 6, preventing the vacuum pump body 6 from being knocked down, thereby causing the connection pipe to be detached, affecting the construction efficiency.

[0064] After use, the stepper motor 33 works in reverse to retract the anti-collision rod 31 to the top of the support structure 2, thereby reducing the floor space occupied at the construction site and facilitating storage and movement.

[0065] At the same time, the anti-collision rod 31 has a buffering effect. When the fixing device is hit, one of the first tension spring 38 and the second tension spring 39 is stretched, and the first anti-collision section 311 and the second anti-collision section 312 rotate relative to each other; when the impact disappears, the stretched tension spring is reset, thereby driving the first anti-collision section 311 and the second anti-collision section 312 to reset, which can effectively buffer and prevent the fixing device from being damaged by impact.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
