Description

Technical Field

[0001] The invention belongs to the technical field of bracket equipment, and in particular relates to a bracket used for mechanical installation. Background Art

[0002] Support brackets are often used in coal mining and transportation construction. Nowadays, most of the brackets used in construction on the market are temporarily built by workers on site using steel pipes. The large number of steel pipes used to build the support brackets are troublesome to store and manage when not in use and are easily damaged, thus wasting a lot of money and human resources. During installation, a large number of steel pipes need to be fixed, and the mechanical equipment is set on the bracket. The bracket cannot provide elastic support for the mechanical equipment, buffering the damage to the bracket caused by gravity, making it inconvenient to use and reducing work efficiency.

[0003] In the prior art, if the bracket is only for shock absorption and stability, springs with different elasticity are directly set under the bracket to provide elastic support for different mechanical equipment. The spring can only be replaced before supporting the equipment. Once the mechanical equipment is installed on the bracket, it cannot be adjusted. If the spring is not suitable, the mechanical equipment must be pulled up again and the spring must be replaced, which is very troublesome. In addition, due to the different forces on the springs, the mechanical equipment is prone to tilt on the bracket, posing a safety hazard. Summary of the invention

[0004] The purpose of the present invention is to provide a bracket for mechanical installation, which solves the problems of inconvenience in use and low working efficiency of the existing bracket.

[0007] The lifting assembly includes a lifting support tube, which is a cylindrical tube structure with an open top. A socket screw passes through the center of the bottom of the lifting support tube. A tray is arranged inside the lifting support tube. The tray is located at the bottom of the lifting support tube, and the tray is threadedly socketed on the screw. A compression spring A is fixedly arranged on the upper surface of the tray, and the compression spring A is socketed on the screw and extends out from the top of the screw.

[0008] A sliding plate is arranged above the compression spring A, a column is fixed vertically at the center of the sliding plate, a compression spring B is sleeved on the column, a buffer pad is arranged on the top of the compression spring B, the buffer pad is clamped and fixed on the upper part of the lifting support tube, the column passes through the buffer pad, and a support plate is arranged on the top of the column extending out of the buffer pad.

[0009] A plurality of raised limiting strips are axially arranged on the inner wall of the lifting support tube, and limiting grooves are correspondingly arranged on the circumferential edges of the tray and the sliding plate. The tray and the sliding plate slide up and down in the lifting support tube along the limiting strips through the limiting grooves.

[0010] The lifting bracket includes a plurality of push rod motors, which are evenly arranged around the outer wall of the lifting support tube, and each push rod motor is inclined with respect to the base.

DETAILED DESCRIPTION

[0020] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Example 1

The servo motor 65 drives the worm 64, drives the worm wheel 63 to rotate, and then drives the screw 61 to rotate, and uses the self-locking characteristics of the worm wheel 63 and the worm 64 to play a role of height locking, and play a role of stable support.

[0023] Example 2

[0024] On the basis of Example 1, Figure 3 and Figure 4 As shown, the lifting assembly 40 includes a lifting support cylinder 20, which is a cylindrical cylinder structure with an opening at the top. The center of the bottom of the lifting support cylinder 20 passes through the sleeve screw 61. A tray 62 is arranged in the lifting support cylinder 20. The tray 62 is located at the bottom of the lifting support cylinder 20. The tray 62 is threadedly sleeved with the screw 61. A shock-absorbing spring is arranged on the bottom of the tray 62, and the shock-absorbing spring abuts against the bottom of the lifting support cylinder 20. A compression spring A50 is fixedly arranged on the upper surface of the tray 62. The compression spring A50 sleeves the screw 61 and extends out of the top of the screw 61. A sliding plate 30 is arranged above the compression spring A50. The center of the sliding plate 30 is vertically fixed with a column 41. The column 41 sleeves the compression spring B70. A buffer pad 43 is arranged on the top of the compression spring B70. The buffer pad 43 is clamped and fixed to the upper part of the lifting support cylinder 20. The column 41 passes through the buffer pad 43. The column 41 extends out of the buffer pad 43 and the support plate 42 is arranged on the top of the buffer pad 43. The elasticity of the compression spring A50 is much greater than that of the compression spring B70.

[0025] A plurality of raised limit strips are axially provided on the inner wall of the lifting support tube 20, and limit grooves are correspondingly provided on the circumferential edges of the tray 62 and the sliding plate 30. The tray 62 and the sliding plate 30 slide up and down along the limit strips in the lifting support tube 20 through the limit grooves. The limit strips are used to limit the rotation of the tray 62 and the sliding plate 30, thereby improving the support stability.

[0026] Example 3

[0027] On the basis of Example 1, the lifting bracket 12 includes multiple push rod motors, and the multiple push rod motors are evenly arranged around the outer wall of the lifting support tube 20. Each push rod motor is tilted with the base 10 to form a support. The multiple push rod motors are synchronously extended and retracted to ensure that the lifting support tube 20 is subjected to uniform force during lifting and lowering, thereby avoiding the lifting support tube 20 from tilting during lifting and lowering. The push rod motor telescopic design has a simple structure, the lifting support tube 20 is lifted and lowered smoothly, and maintenance is convenient.

[0028] Different mechanical equipment uses base plates 11 of different sizes. The corresponding lifting components 40 are installed on the base plates 11 according to the number of legs of the mechanical equipment to improve applicability.

[0029] The bottom plate 11 is a square steel plate structure with a thickness of 8 mm.

[0030] The working principle of the bracket for mechanical installation of the present invention is as follows: through four lifting components 40 around the base plate 11, each lifting component 40 includes a lifting support tube 20, and a sliding plate 30 is slidably connected inside the lifting support tube 20, and a compression spring B70 and a compression spring A50 are respectively arranged at the upper and lower ends of the sliding plate 30; a servo motor 65 is arranged on the base 10, and the servo motor 65 controls the rotation of the screw 61, the screw 61 is rotatably connected to the lifting support tube 20, and the tray 62 is screwed to the screw 61, and the tray 62 is movably pressed against the spring A50; when the screw 61 rotates, since the tray 62 cannot rotate, the tray 62 is driven to rise and fall vertically, which has the effect of adjusting the pre-compression amount of the spring A50; the lifting support tube 20 is driven to rise and fall; no matter when it is shipped or installed on the ground, the pre-compression amount of the spring A50 can be adjusted in real time through the lifting support tube 20 to change the support elasticity, thereby obtaining good support and shock absorption, and being more convenient to use. The lifting bracket 12 adjusts the rising height of the lifting support tube 20. At the same time, the servo motor 65 drives the screw 61 to rotate and drives the lifting support tube 20 to move up and down. The height of the device is adjusted as needed. The push rod motor is combined with the servo motor 65 to adjust the height of the lifting support tube 20 to the greatest extent. Compared with traditional devices, there is no need to use steel pipes for construction, which saves time, improves work efficiency, saves manpower and material resources, reduces costs, and reduces the risk factor.

[0031] The working process of the bracket for mechanical installation of the present invention is as follows: when in use, when lifting mechanical equipment of different models and different weights, the mechanical equipment is lifted on the support plate 42. When the mechanical equipment is close to the support plate 42 for support, the compression spring B70 is compressed by gravity, and the gravity is transferred to the sliding plate 30. The sliding plate 30 slides downward along the limit bar in the lifting support cylinder 20, and the compression spring A50 is deformed for buffering. Because the compression spring A50 is sleeved on the screw rod 61 and extends out of the top of the screw rod 61, the tray 62 slides downward for buffering after being stressed, and the servo motor 65 is used to drive the worm 64 to rotate, and the meshing worm wheel 63 drives the screw rod 61 to rotate. The servo motor 65 is used to drive the worm 64 to rotate, and each compression spring A50 is adjusted by the corresponding servo motor 65, and is adjusted separately according to the operating status of the equipment, which is beneficial to improving the shock absorption effect. The compression spring A50 is slowly moved upward by the tray 62 to release elastic potential energy, thereby achieving the purpose of smooth shock absorption; the compression spring A50, the sliding plate 30 and the compression spring B70 are pressed against the upper end of the lifting support tube 20 by using the tray 62, and the sliding plate 30 is pre-compressed, and the elasticity is adjusted in real time. There is no need to re-lift the mechanical equipment. During shipment, the pre-compression amount is reduced, which has a good shock absorption effect. When installed on the ground, the servo motor 65 is linked to the operation of the mechanical equipment to adjust the elasticity in real time, which has a better shock absorption effect.

[0032] The present invention is used for mechanical installation of brackets. The lifting support tube 20 provides a movable space for the compression spring B70 and the compression spring A50 to reduce shock, so that the loading and unloading transfer of mechanical equipment is stable and efficient. The pre-compression amount of the compression spring A50 can be adjusted in real time through the lifting assembly 40 to change the support elasticity, thereby obtaining good support and shock absorption, good stability, and more convenient use. Under the joint action of the compression spring B70, the compression spring A50, and the buffer pad 43, the stability of the support plate 42 is maintained, making the operation safer. The lifting bracket 12 supports and prevents the lifting support tube 20 from sliding during operation, thereby improving safety.
