Description

Technical Field

[0001] The utility model relates to the technical field of air compressor protection, in particular to a protective device for an air compressor. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. When the compressor is working, air is sucked in through a self-cleaning air filter, and the filter is automatically cleaned by the PLC. The air enters the first stage of compression after automatic adjustment by the inlet guide vane. The gas temperature after the first stage of compression is relatively high, and then enters the intercooler for cooling (water goes inside the pipe, gas goes outside the pipe, and the water flow rate of the intercooler is required to be 110m / h) before entering the second stage of compression system. In order to prevent the gas in the system from pouring into the compression chamber (avoid starting under pressure), a suspended full-open check valve is installed on the exhaust pipe of the compressor. The gas discharged from the compressor pushes the check valve open and enters the exhaust muffler, then enters the first stage aftercooler, the second stage aftercooler, and then enters the exhaust main pipe.

[0003] Publication No. "CN220434957U" provides a protective device for an air compressor. The movable slide rod is no longer pulled, so that the movable slide rod is reset by the elastic force of the reset spring, and then the movable slide rod moves downward, so that the first arc-shaped movable plate moves downward, and at the same time, the second arc-shaped movable plate and the first arc-shaped movable plate move relative to each other, so that the two arc-shaped rubber pads contact the surface of the connected rotating shaft, and then the two arc-shaped rubber pads rub against the surface of the connected rotating shaft, so as to facilitate the restriction of the connected rotating shaft, and then the movable wheel is restricted to prevent the movable wheel from moving automatically and causing the air compressor to collide with other objects.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the protective device for the air compressor can prevent the movable wheel from moving automatically by the friction between the arc-shaped rubber pad and the surface of the connecting rotating shaft, this positioning structure requires the staff to constantly lift the movable slide bar to enable the connecting rotating shaft to rotate normally during the pushing process of the air compressor, thereby increasing the labor intensity of the staff during the transfer process. Secondly, the air compressor does not have a corresponding shock-absorbing structure to buffer and suppress resonance, resulting in a large resonance noise during the operation of the air compressor, and its practicality needs to be improved. Utility Model Content

[0006] The purpose of the utility model is to provide a protective device for an air compressor to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A protective device for an air compressor comprises an air compressor body, a bottom support plate, universal wheels and a heightening seat, wherein a bottom support plate is installed at the bottom of the air compressor body, and the heightening seats are symmetrically fixedly connected to the left and right sides of the lower end surface of the bottom support plate, and a universal wheel is installed at the lower end of the heightening seat. A positioning assembly for supporting the air compressor body is arranged at the lower end of the bottom support plate to prevent the air compressor body from being displaced during operation, and a shock-absorbing assembly is arranged between the bottom support plate and the positioning assembly, and the shock-absorbing assembly is used to reduce the resonance noise of the air compressor body when it is working.

[0009] Preferably, the positioning assembly includes a positioning support plate, a linkage plate, a limiting cylinder, a transmission worm gear, a torque motor, a rotating screw and a transmission worm gear. The torque motor is installed on the right side inside the bottom support plate, and the left end of the torque motor is connected to the transmission worm gear.

A limiting cylinder is installed on the lower side of the annular side of the rotating screw gear, a linkage plate is arranged at the bottom of the limiting cylinder, and a positioning support plate is installed below the linkage plate.

[0010] Preferably, a follower plate is provided at the upper end of the rotating screw rod, and annular blocking covers are symmetrically installed on the left and right sides of the lower end surface of the bottom support plate.

[0011] Preferably, the anti-vibration assembly includes a rubber isolation pad, a shock absorbing seat and an anti-slip bottom pad. The shock absorbing seat is installed between the linkage plate and the positioning support plate. The anti-slip bottom pad is pasted on the lower end surface of the positioning support plate, and the rubber isolation pad is pasted on the upper end surface of the bottom support plate.

[0014] Preferably, push handles are fixedly connected to both left and right ends of the air compressor body, and a control panel is installed on the left side of the front end surface of the bottom support plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model drives the transmission worm to reverse through the torque motor, so that the transmission worm can drive the rotating screw to reverse through the transmission worm wheel. At this time, the rotating screw can drive the positioning support plate to descend together through the limit cylinder, the linkage plate and the shock-absorbing seat. When the positioning support plate descends to a certain distance, the bottom support plate will be lifted to separate the universal wheel from the external ground, so as to support and position the bottom support plate, thereby avoiding displacement of the air compressor body and collision with other objects during operation, thereby improving the protection effect of the air compressor body, and the structure saves time and effort during operation, and has good practicality;

[0017] 2. The utility model avoids the resonance noise between the air compressor body and the bottom support plate by sticking the rubber isolation pad. By installing the shock-absorbing seat, most of the vibrations transmitted by the linkage plate can be isolated. The anti-skid bottom pad not only makes the lower end surface of the positioning support plate more anti-skid, but also avoids the resonance noise between the positioning support plate and the external ground, thereby reducing the resonance noise generated by the air compressor body when working.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] Embodiment 1:

[0027] A protective device for an air compressor comprises an air compressor body 1, a bottom support plate 3, a universal wheel 6 and a heightening seat 7. A bottom support plate 3 is installed at the bottom of the air compressor body 1, and the bottom support plate 3 supports the air compressor body 1. The lower end surface of the bottom support plate 3 is symmetrically fixedly connected with the heightening seat 7 on both sides. The heightening seat 7 is connected to the bottom support plate 3 by welding. The heightening seat 7 facilitates the universal wheel 6 to support the bottom support plate 3. A universal wheel 6 is installed at the lower end of the heightening seat 7. The universal wheel 6 makes the transfer of the air compressor body 1 more labor-saving and convenient. Push handles 2 are fixedly connected to the left and right ends of the air compressor body 1. The push handles 2 are connected to the air compressor body 1 by welding. The push handles 2 facilitate the staff to push and pull the air compressor body 1 by hand.

[0028] A control panel is installed on the left side of the front end surface of the bottom support plate 3, and the control panel is connected to the torque motor 46 through a wire. The control panel facilitates the staff to control the forward and reverse rotation of the torque motor 46. Since the working principle and internal detailed structure of the control panel are relatively mature technologies in the prior art, they will not be elaborated here. A positioning assembly 4 for supporting the air compressor body 1 is provided at the lower end of the bottom support plate 3 to prevent the air compressor body 1 from being displaced during operation. A shock-absorbing assembly 5 is provided between the bottom support plate 3 and the positioning assembly 4, and the shock-absorbing assembly 5 is used to reduce the resonance noise of the air compressor body 1 during operation.

[0029] The positioning assembly 4 includes a positioning support plate 41, a linkage plate 42, a limiting cylinder 43, a transmission worm gear 45, a torque motor 46, a rotating screw 48 and a transmission worm 49. A torque motor 46 is installed on the right side inside the bottom support plate 3. The torque motor 46 will drive the transmission worm 49 to rotate. The left end of the torque motor 46 is connected to the transmission worm 49, and the transmission worm 49 will drive the transmission worm gear 45 to rotate. The front side of the annular side of the transmission worm 49 is meshed with a transmission worm gear 45, and the transmission worm gear 45 will drive the rotating screw 48 to rotate. A rotating screw 48 is arranged inside the transmission worm gear 45, and the rotating screw 48 is connected to the follower plate 47 and the transmission worm gear 45 by welding. An internal thread is arranged on the inner annular side of the limiting cylinder 43, and the internal thread is meshed with the rotating screw 48. The meshed internal thread and the rotating screw 48 facilitate the rotating screw 48 to drive the limiting cylinder 43 to move up and down.

[0030] A limiting cylinder 43 is installed on the lower side of the annular side of the rotating screw rod 48. The limiting cylinder 43 can move downward a distance greater than the distance between the positioning support plate 41 and the external ground. The limiting cylinder 43 will drive the linkage plate 42 to move up and down. A linkage plate 42 is arranged at the bottom of the limiting cylinder 43. The linkage plate 42 and the limiting cylinder 43 are connected by welding. The linkage plate 42 will drive the shock-absorbing seat 52 to move up and down. A positioning support plate 41 is installed under the linkage plate 42, and the positioning support plate 41 will support the shock-absorbing seat 52. A follower plate 47 is arranged on the upper end of the rotating screw rod 48, and annular blocking covers 31 are symmetrically installed on the left and right sides of the lower end surface of the bottom support plate 3. The follower plate 47 and the annular blocking cover 31 prevent the rotating screw rod 48 from shaking or displacing during use. A ball bearing is installed on the annular side of the follower plate 47. The ball bearing makes the follower plate 47 rotate smoothly. A reinforcing plate 44 is fixedly connected to the lower side of the annular side of the limiting cylinder 43. The reinforcing plate 44 makes the support stability of the limiting cylinder 43 better.

[0031] Embodiment 2:

[0032] On the basis of Example 1, in this embodiment, a rubber isolation pad 51 is pasted to avoid resonance noise between the air compressor body 1 and the bottom support plate 3. By installing a shock-absorbing seat 52, most of the vibrations transmitted from the linkage plate 42 are isolated. The anti-slip bottom pad 53 not only makes the lower end surface of the positioning support plate 41 more anti-slip, but also avoids resonance noise between the positioning support plate 41 and the external ground, thereby reducing the resonance noise generated when the air compressor body 1 is working.

[0033] The anti-vibration assembly 5 includes a rubber isolation pad 51, a shock-absorbing seat 52 and an anti-skid bottom pad 53. The shock-absorbing seat 52 is installed between the linkage plate 42 and the positioning support plate 41. The shock-absorbing seat 52 is made of a damping shock absorber. The shock-absorbing seat 52 made of a damping shock absorber has the advantages of composite vibration isolation and noise reduction, low natural frequency and good vibration isolation effect, so that the shock-absorbing seat 52 can isolate most of the vibrations transmitted from the linkage plate 42. The anti-skid bottom pad 53 is pasted on the lower end surface of the positioning support plate 41. The anti-skid bottom pad 53 is made of an anti-skid rubber pad. The anti-skid bottom pad 53 made of an anti-skid rubber pad has the ability of isolation and anti-skid, which not only makes the lower end surface of the positioning support plate 41 more anti-skid, but also avoids the generation of resonance noise between the positioning support plate 41 and the external ground. The rubber isolation pad 51 is pasted on the upper end surface of the bottom support plate 3. The rubber isolation pad 51 avoids resonance between the air compressor body 1 and the bottom support plate 3.

[0034] Working principle: When the air compressor body 1 is pushed to the desired position, first connect the air compressor body 1 and the control panel to the external fixed power supply, and then control the torque motor 46 to reverse through the control panel, so that the torque motor 46 drives the transmission worm 49 to reverse together, and then the transmission worm 49 will drive the transmission worm wheels 45 on the left and right sides to reverse together, so that the transmission worm wheels 45 drive the rotating screw rods 48 on the left and right sides to reverse synchronously, and at this time, the reversed rotating screw rods 48 will cause the limit cylinders 43 on the left and right sides to descend synchronously, and the limit The positioning cylinder 43 will drive the positioning support plate 41 to descend together through the linkage plate 42 and the shock-absorbing seat 52. When the positioning support plate 41 descends to the anti-slip bottom pad 53 and fits the external ground, the bottom support plate 3 will be lifted so that the bottom support plate 3 can pull the universal wheel 6 through the heightening seat 7. The universal wheel 6 is separated from the external ground and the torque motor 46 can be stopped to support and position the bottom support plate 3 to avoid displacement of the air compressor body 1 during operation. During the operation of the air compressor body 1, the rubber shock-absorbing seat 52 is used to prevent the air compressor body 1 from being displaced. The pad 51 prevents resonance between the air compressor body 1 and the bottom support plate 3, and the shock-absorbing seat 52 made of a damping shock absorber can isolate most of the vibrations transmitted by the linkage plate 42. At the same time, the anti-skid bottom pad 53 made of an anti-skid rubber pad not only makes the lower end surface of the positioning support plate 41 more anti-skid, but also prevents resonance noise between the positioning support plate 41 and the external ground, thereby reducing the resonance noise generated by the air compressor body 1 when it is working; when the air compressor body 1 needs to be moved again, the staff first controls the torque motor 46 The forward rotation causes the transmission worm 49 to drive the rotating screw 48 to rotate forward through the transmission worm wheel 45. At this time, the rotating screw 48 that rotates forward will drive the limit cylinder 43 to move upward, and then the limit cylinder 43 drives the positioning support plate 41 to move upward through the linkage plate 42 and the shock-absorbing seat 52. During the upward movement of the positioning support plate 41, the universal wheel 6 will descend and contact the external ground, and the anti-slip bottom pad 53 will be moved up until it is separated from the external ground. At this time, the power supply of the air compressor body 1 and the control panel is disconnected, and then the air compressor body 1 can be pushed again.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
