Description

Technical Field

[0001] The utility model relates to the technical field of stacker-reclaimers, in particular to a circular stacker-reclaimer cab shock-absorbing support. Background Art

[0002] Circular stackers and reclaimers are used in circular coal yards and perform both stacking and reclaiming functions. The operator's cab is located high up and rigidly connected to the machine's main steel structure. This creates vibrations that are directly transmitted to the cab during operation, impacting operator comfort, reducing accuracy and efficiency, and impacting various precision equipment within the cab, shortening its service life.

[0003] Conventional shock absorption measures use damping springs to support the driver's cab. This is a single damping method and its effectiveness needs to be improved. If the damping springs fail, the driver's cab will fall directly, impacting the equipment and posing a safety hazard. Summary of the Invention

[0004] In order to solve the problem that conventional shock absorption methods are single and have no safety protection, the utility model provides a circular stacker-reclaimer cab shock-absorbing support, which adopts spring shock absorbers to evenly and reliably bear the load on the cab, playing a shock-absorbing and buffering role. At the same time, the rubber buffer block can prevent the equipment from being impacted by the failure of the shock absorber, thereby improving the safety of the shock absorption of the cab.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0006] A circular stacker-reclaimer cab shock-absorbing support comprises a steel base, a rubber ring, a spring shock absorber and a rubber buffer block. The rubber ring is provided on the steel base, and the rubber ring fits the inner wall of the steel base. The spring shock absorbers are provided on the inner periphery of the steel base, and there are at least two spring shock absorbers on each side of the steel base.

[0007] The rubber buffer blocks are also arranged around the steel base. There is at least one rubber buffer block on each side of the steel base, and the rubber buffer blocks are arranged between at least two spring shock absorbers. The lower part of the driver's cab is embedded in the steel base, and the lower side of the driver's cab is fitted with the rubber ring to prevent wear caused by contact with the steel base. The spring shock absorbers around the steel base cooperate with the supporting driver's cab to support and absorb shock to the driver's cab. There is a gap between the lower part of the driver's cab and the rubber buffer blocks above and below to prevent the driver's cab from falling and impacting the steel base.

[0008] Furthermore, the steel base is a rectangular groove structure made of steel plate. The edge contour of the steel base is compatible with the lower contour of the driver's cab, making it easy to insert the driver's cab into the steel base. The rubber ring is a rectangular ring made of rubber pads. The rubber ring extends vertically from the top of the steel base to the bottom of the steel base. No matter how the driver's cab moves up and down, it will contact the rubber ring.

[0009] Furthermore, there are two spring shock absorbers on each side of the steel base, and the two spring shock absorbers are arranged at intervals. Each spring shock absorber includes a shock-absorbing top plate, a shock-absorbing bottom plate and a shock-absorbing spring. The shock-absorbing top plate and the shock-absorbing bottom plate are arranged in parallel up and down. The shock-absorbing top plate is bolted to the driver's cab, and the shock-absorbing bottom plate is bolted to the steel base, which facilitates the installation of the spring shock absorber. The shock-absorbing spring is arranged between the shock-absorbing top plate and the shock-absorbing bottom plate. There are multiple shock-absorbing springs arranged at intervals, providing reliable support force and shock-absorbing effect.

[0010] Furthermore, the shock-absorbing top plate and the shock-absorbing bottom plate are both composite plates. The shock-absorbing top plate includes stacked steel plates and rubber plates. The shock-absorbing bottom plate and the shock-absorbing top plate have the same structure. The rubber plate is bonded to the upper surface of the steel plate of the shock-absorbing top plate, and the rubber plate is bonded to the lower surface of the steel plate of the shock-absorbing bottom plate.

[0011] Furthermore, hydraulic cylinders for lifting the driver's cab are provided at the corners of the steel base, which facilitates lifting the driver's cab when inspecting and maintaining the spring shock absorber.

[0012] Through the above technical solution, the beneficial effects of the utility model are:

[0013] This utility model features a rationally designed structure. The lower portion of the driver's cab is embedded within the steel base, limiting its deflection and allowing only vertical movement. A rubber ring is also positioned on the inner wall of the steel base, creating contact with the cab to prevent friction between the cab and the steel base during vertical movement. Eight spring shock absorbers are evenly spaced around the steel base, working together to support the cab and effectively reducing shock to the cab through expansion and contraction.

[0014] To prevent the risk of spring shock absorber failure, this utility model evenly arranges rubber buffer blocks around the steel base. The driver's cab is normally supported by the spring shock absorber. If the spring shock absorber fails, the driver's cab falls onto the rubber buffer blocks, which can prevent the driver's cab from directly impacting the steel base, ensuring the safety of the spring shock absorber support. Hydraulic cylinders are arranged at the corners of the steel base to raise or lower the driver's cab, facilitating maintenance, inspection, and replacement of shock-absorbing components inside the steel base.

DETAILED DESCRIPTION

[0022] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings:

[0023] like Figures 1 to 6 The figure shows a circular stacker / reclaimer cab shock-absorbing support, comprising a steel base 1, a rubber ring 2, a spring shock absorber 3, and a rubber buffer 4. Steel base 1 supports the cab 11 and is a rectangular groove structure made of steel plate. Its upper end is open, and its edge contour matches the lower contour of cab 11, allowing the lower portion of cab 11 to fit within it. This secures steel base 1, limiting lateral displacement of cab 11.

[0024] Steel base 1 is equipped with a rubber ring 2, a rectangular ring made of a rubber pad. Rubber ring 2 is in contact with the inner walls of steel base 1, extending vertically from the top to the bottom of steel base 1. The lower perimeter of cab 11 is also in contact with rubber ring 2. Rubber ring 2 is positioned between the inner walls of steel base 1 and the lower outer wall of cab 11, providing wear protection and vibration isolation. This prevents friction between cab 11 and steel base 1 when it moves up and down, and also reduces the transmission of vibration.

[0025] Spring shock absorbers 3 are arranged around the steel base 1. There are at least two spring shock absorbers 3 on each side of the steel base 1. Here, there are two spring shock absorbers 3 on each side of the steel base 1, and the two spring shock absorbers 3 are arranged at intervals. The spring shock absorbers 3 around the steel base 1 cooperate to support the driver's cab 11, and then the eight spring shock absorbers 3 jointly support the driver's cab 11, playing a role in reducing the shock of the driver's cab 11. Figures 1 to 3 shown.

[0026] In this embodiment, each spring shock absorber 3 includes a shock absorbing top plate 31, a shock absorbing bottom plate 32 and a shock absorbing spring 33. The shock absorbing top plate 31 and the shock absorbing bottom plate 32 are arranged in parallel up and down, and a shock absorbing spring 33 is provided between the shock absorbing top plate 31 and the shock absorbing bottom plate 32. The shock absorbing springs 33 are arranged in three intervals. The spring shock absorber 3 can play a supporting and shock absorbing role for the driver's cab 11. Figure 4 shown.

[0027] When the shock absorber is installed, the shock-absorbing top plate 31 is bolted to the driver's cab 11, and the shock-absorbing bottom plate 32 is bolted to the steel base 1, thereby achieving the installation of the spring shock absorber 3 between the driver's cab 11 and the steel base 1. In order to avoid the rigid connection of the spring shock absorber, the shock-absorbing top plate 31 and the shock-absorbing bottom plate 32 are both composite plates. The shock-absorbing top plate 31 includes a steel plate and a rubber plate. The shock-absorbing bottom plate 32 and the shock-absorbing top plate 31 have the same structure. The rubber plate is bonded to the upper surface of the steel plate of the shock-absorbing top plate 31, thereby making flexible contact with the driver's cab 11. The rubber plate is bonded to the lower surface of the steel plate of the shock-absorbing bottom plate 32, thereby making flexible contact with the steel base 1, which can also achieve a shock-absorbing effect.

[0028] This utility model utilizes multiple spring shock absorbers 3 to evenly support the driver's cab 11, ensuring reliable load bearing and providing shock absorption. The damping springs 33 in each spring shock absorber 3, along with the composite structure of the damping top plate 31 and bottom plate 32, provide a dual shock absorption effect. The rubber rings 2 surrounding the steel base 1 and between the driver's cab 11 also provide a seismic isolation function. The steel base 1 also restricts the vertical movement of the driver's cab 11, further reducing shock absorption.

[0029] In order to avoid shock absorption failure, rubber buffer blocks 4 are arranged around the steel base 1. There is at least one rubber buffer block 4 on each side of the steel base 1. Here, there is one rubber buffer block 4 on each side of the steel base 1. The rubber buffer block 4 is a rectangular block made of rubber material. The rubber buffer block 4 is arranged between at least two spring shock absorbers 3.

[0030] In the initial state, the driver's cab 11 is supported by the spring shock absorber 3, and there is a gap between the lower part of the driver's cab 11 and the rubber buffer block 4. If the spring shock absorber 3 fails, the driver's cab 11 falls and contacts the rubber buffer block 4, which supports the driver's cab 11 and prevents it from directly impacting the steel base 1.

[0031] To prevent the rubber buffer block 4 from shifting, sockets 5 are provided at the four corners of the rubber buffer block 4. The sockets 5 pass through the rubber buffer block 4. Each socket 5 is provided with a rod 6. The rod 6 is shorter than the socket 5. The lower end of the rod 6 is fixedly connected to the steel base 1. The rubber buffer block 4 is prevented from moving under the restriction of the rod 6.

[0032] On this basis, a buffer steel plate 7 with a certain elasticity is also provided above the rubber buffer block 4. The buffer steel plate 7 is bent into an arch shape, and the ends of the buffer steel plate 7 are horizontal plates. Two sockets 8 are provided below each end of the buffer steel plate 7. The two sockets 8 are respectively inserted into the socket 5 and sleeved above the plug rod 6. The middle part of the rubber buffer block 4 is opened and provided with a compression spring 9. The upper end of the compression spring 9 is against the middle part of the lower part of the buffer steel plate 7. Figure 5 and Figure 6 shown.

[0033] As a result, if the spring shock absorber 3 fails, the driver's cab 11 will first fall and contact the buffer steel plate 7, exerting downward pressure on the buffer steel plate 7. Since the buffer steel plate 7 is arched, it can effectively disperse the pressure. Moreover, with the support of the compression spring 9, the buffer steel plate 7 is not easily deformed, and can cushion the driver's cab 11. This is equivalent to adding a buffering measure during the process of the driver's cab 11 falling to the rubber buffer block 4, which can reduce the huge impact force generated by the driver's cab 11 falling too quickly, ensure the stability of the driver's cab 11, and protect the driver's cab 11 from rigid impact, thereby preventing damage to precision equipment.

[0034] Because the driver's cab 11 is embedded in the steel base 1, which has internal shock-absorbing measures such as spring shock absorbers 3, hydraulic cylinders 10 are installed at the corners of the steel base 1 to facilitate the inspection, maintenance, and replacement of the shock-absorbing measures. Therefore, there are four hydraulic cylinders 10 for lifting the driver's cab 11. When the four hydraulic cylinders 10 are retracted, the spring shock absorbers 3 support the driver's cab 11. When the four hydraulic cylinders 10 are extended simultaneously, they can prop the driver's cab 11 up and away from the steel base 1, thereby exposing the shock-absorbing measures inside the steel base 1.

[0035] The utility model reduces the intensity of the vibration generated during the operation of the stacker and reclaimer equipment and transmitted to the driver's cab 11 by adding a shock-absorbing support, thereby maintaining the stability of the driver's cab 11, thereby increasing the service life of various precision equipment in the driver's cab 11, and for the driver working in the driver's cab 11 for a long time, it can improve the comfort of the working environment, the accuracy of the driver's operation and the work efficiency.

[0036] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
