Aiming at the deficiencies in the prior art, the utility model provides a new garbage crane cable stress protection device with simple structure, reasonable design and good use effect.

According to the design scheme provided by the utility model, a new type of garbage crane cable force protection device includes a housing and a force-bearing unit arranged in the housing. The unit includes a double-ended screw and a pressure spring set on the double-ended screw. One end of the double-ended screw is fixed with an inner nut, and the other end extends to the outside of the housing and is fixed with an adjusting nut. One end of the pressure spring presses against the inner nut. One end is pressed against the inner wall of the housing end.

As mentioned above, the inside of the housing is also fixed with a pressure detection unit that is signal-connected to the garbage crane control cabinet.

As mentioned above, one end of the housing is also provided with a protective cover, the end of the protective cover is fixed with a lifting ring, the adjusting nut is a nut with a ring, and the two ends of the housing are respectively fixed with the cable of the garbage grab head through the lifting ring and the nut with a ring.

As mentioned above, the shell is a closed tubular shell, one end of the tubular shell is provided with a double-ended screw mounting hole, the other end is fixed with a protective cover, the end of the protective cover is fixed with a lifting ring, and the adjusting nut is a ring nut , the two ends of the shell are fixed with the cable of the garbage grab head through the lifting ring and the ring nut respectively.

Preferably, the connection between the other end of the tubular housing and the protective cover is provided with an installation hole for fixing the pressure detection unit, and the pressure detection unit is fixed in the tubular housing through the installation hole.

As mentioned above, the pressure detection unit is an inductive proximity switch.

Beneficial effects of the utility model garbage crane cable stress protection device:

The utility model has a simple structure, novel and reasonable design, and when the garbage grab head cable is stressed abnormally, the double-headed screw moves upward, and the inductive proximity switch starts to act, preventing the grab bucket of the garbage hoist from rising and avoiding grabbing. When the cable of the bucket breaks, the adjusting nut can change the force of the compression spring when it deforms and compresses, so that abnormal operation of the cable can be detected in time, the service life of the cable can be prolonged, and the manufacturing is simple and the cost is low.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a schematic diagram of the use state of the utility model.

Detailed ways:

In the figure, the number 1 represents the housing, the number 2 represents the pressure spring, the number 3 represents the pressure detection unit, the number 41 represents the double-ended screw, the number 42 represents the inner nut, the number 43 represents the adjustment nut, the number 5 represents the protective cover, and the number 6 represents the suspension ring , and the number 7 represents the garbage grab cable.

The utility model will be further described in detail below in conjunction with the accompanying drawings and technical solutions, and the implementation of the utility model will be described in detail through preferred embodiments, but the implementation of the utility model is not limited thereto.

Embodiment 1, as shown in Figures 1 to 2, a new type of garbage crane cable force protection device, including a housing and a force unit arranged in the housing, the two ends of the housing are respectively fixedly connected to the garbage grab head cable, The force unit includes a double-ended screw and a pressure spring set on the double-ended screw. One end of the double-ended screw is fixed with an inner nut, and the other end extends to the outside of the housing and is fixed with an adjusting nut. One end of the pressure spring presses against the inner nut. , the other end is pressed against the inner wall of the end of the shell. When the cable of the garbage grab head is stressed for some reason, it can buffer the force of the cable to avoid the breakage of the cable of the garbage grab head caused by sudden lifting, which will affect the normal operation. work flow.

A pressure detection unit that is signal-connected to the garbage crane control cabinet is also fixed inside the housing.

One end of the housing is also provided with a protective cover, the end of the protective cover is fixed with a suspension ring, the adjusting nut is a nut with a ring, and the two ends of the housing are respectively fixed with the cable of the garbage catcher through the suspension ring and the nut with a belt.

The casing is a closed tubular casing, one end of the tubular casing is provided with a double-ended screw installation hole, and the other end is fixed to the protective cover.

An installation hole for fixing the pressure detection unit is provided at the connection between the other end of the tubular housing and the protective cover, and the pressure detection unit is fixed in the tubular housing through the installation hole.

As mentioned above, the pressure detection unit is an inductive proximity switch.

The utility model has the advantages of simple structure, novel and reasonable design. When the cable of the garbage grab head is under abnormal force, the double-headed screw moves upwards, and the inductive proximity switch starts to act, preventing the garbage crane from rising and avoiding the breakage of the grab cable. The adjusting nut can The power of the compression spring is changed during deformation and compression, the abnormal operation of the cable is detected in time, the service life of the cable is prolonged, and the manufacture is simple and the cost is low.

The utility model is not limited to the above-mentioned specific implementation, and those skilled in the art can also make various changes accordingly, but any equivalent or similar changes to the utility model should be covered within the scope of the claims of the utility model.
