Description

Technical Field

[0001] The invention relates to the technical field of hoist installation equipment, in particular to an automatic filling system for lining blocks for a hoist sheave. Background Art

[0002] Multi-rope friction hoists are widely used in mine hoisting equipment. They adopt double-layer cages and counterweights for mutual balanced lifting. They are mainly composed of drums, electronic control equipment, reducers, motors, wire ropes, shaft towers, shaft equipment, guide wheels (hereinafter referred to as the head sheave), etc. Since the head sheave is in direct contact with the wire rope, when the wire rope pulls a heavy object, it needs to be placed in the groove on the head sheave to realize the steering of the wire rope. Since the heavy object is heavy, the wire rope exerts a greater pressure on the head sheave, so the friction between the two will also be greater. Since the hardness of the head sheave is relatively large, the wire rope will wear after being used for a period of time, and eventually the wire rope will break and cause an operational accident. For this reason, people lay a layer of lining blocks at the bottom of the groove of the head sheave. The hardness of the lining block material is less than that of the wire rope and the head sheave. The lining block replaces the head sheave to achieve contact and friction with the wire rope, thereby causing wear of the lining block. The lining block is replaced regularly to avoid friction between the wire rope and the head sheave.

[0003] Most of the lining blocks currently in use have a trapezoidal cross-section that is narrow at the top and wide at the bottom. To prevent the lining blocks from falling out of the groove on the sheave, the groove is also a trapezoidal shape that is narrow at the top and wide at the bottom. To install the lining blocks into the groove, mounting holes are provided on the sidewalls of the groove. The lining blocks are then inserted into the groove from the side of the sheave through the mounting holes to achieve installation, and the mounting holes are then sealed. Since a lining block is composed of two symmetrical small lining blocks, during installation, one small lining block must first be inserted into the groove, and then the second small lining block must be inserted into the groove in a symmetrical direction to form a complete lining block with the first small lining block. During this process, tools must be used to press or tap the lining blocks to ensure that the two small lining blocks are aligned and fit tightly together. This is a very stringent requirement, and the installation of the lining blocks is laborious and time-consuming.

[0004] Therefore, it is necessary to propose a time-saving and labor-saving lining block installation device to reduce the difficulty of lining block installation. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem of time-consuming and labor-intensive lining block installation in the prior art, and an automatic lining block filling system for a hoist sheave is provided.

[0006] The technical solution of the present invention is:

[0007] An automatic filling system for lining blocks for a hoist sheave includes a shell, a cavity matching the size of the lining block is provided in the shell, a feed port is provided on the top of the shell, a discharge port is provided at one end of the shell, both the feed port and the discharge port are connected to the cavity, a first pushing device is provided in the cavity, a first push plate is connected to the first pushing device, the discharge port is connected to the sheave groove, the first pushing device drives the first push plate to push the lining block to move in the cavity, and the lining block enters the sheave groove after passing through the discharge port.

[0008] Furthermore, a second pushing device is provided on the shell, the second pushing device is connected to a second push plate, the second push plate is located in the groove of the sky wheel, and the second pushing device drives the second push plate to move in the groove of the sky wheel, thereby approaching or moving away from the discharge port.

[0009] Furthermore, the second pushing device is connected to a baffle, and a notch is provided on the side wall of the cavity near the discharge port. The second pushing device drives the baffle to pass through the notch to squeeze the side of the liner block, so that the two small liner blocks that make up the liner block are aligned.

[0010] Furthermore, the second pushing device drives the second push plate and the baffle to move at the same time. When the baffle squeezes the side of the lining block, the second push plate approaches the discharge port and is located on one side of the discharge port. When the lining block passes through the discharge port and enters the groove of the sky wheel, the second push plate pushes the lining block away from the discharge port.

[0011] Furthermore, the baffle and the second push plate are integrated.

[0012] Furthermore, the height of the cavity matches the height of the lining block, and the two are clearance-fitted.

[0013] Furthermore, the first pushing device is a cylinder.

[0014] Furthermore, the second pushing device is a cylinder.

[0015] Furthermore, the shell is fixedly connected to the side wall of the sheave via fasteners.

[0016] Furthermore, the cavity and the lining block are clearance-fitted.

[0017] The automatic filling system for the hoist sheave of the present invention has a cavity in the shell that matches the size of the liner, and the liner is placed in the cavity through the feed port, and the first push plate is driven by the first pushing device to move the liner in the cavity. After the liner passes through the discharge port, it enters the groove from the groove on the side of the sheave. Since the liner moves completely in the cavity during the assembly process, and the internal space of the cavity is the same size as the liner, the two small liner blocks will not be scattered during the movement of the liner in the cavity until they enter the sheave groove, thereby realizing the installation of the liner. Compared with traditional technology, this technical solution only needs to put the two spliced ​​small liner blocks into the feed port as a complete liner, and how the liner blocks are accurately entered into the sheave groove is automatically completed by the equipment, which replaces the process of using tools to press or knock the liner blocks, and also ensures that the two small liner blocks are aligned and tightly fit, meeting quality requirements, and making the installation of the liner blocks time-saving and labor-saving.

[0023] In order to make the technical means, technical features, invention objectives and technical effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0024] Example 1:

[0025] like Figure 1 and Figure 2As shown, this embodiment provides an automatic filling system for lining blocks for a hoist sheave, comprising a shell 1, wherein a cavity 2 matching the size of the lining block is provided in the shell 1, a feed port 3 is provided on the top of the shell 1, and a discharge port 4 is provided at one end of the shell 1, both the feed port 3 and the discharge port 4 are connected to the cavity 2, a first pushing device 5 is provided in the cavity 2, a first push plate 7 is connected to the first pushing device 5, the discharge port 4 is connected to the sheave groove 8, the first pushing device 5 drives the first push plate 7 to push the lining block to move in the cavity 2, and the lining block enters the sheave groove 8 after passing through the discharge port 4.

[0026] Preferably, a second pushing device 6 is provided on the shell 1, and the second pushing device 6 is connected to a second push plate 9, and the second push plate 9 is located in the crown wheel groove 8. The second pushing device 6 drives the second push plate 9 to move in the crown wheel groove 8, thereby approaching or moving away from the discharge port 4.

[0027] Preferably, the second pushing device 6 is connected to a baffle 10, and a notch 11 is provided on the side wall of the cavity 2 near the discharge port 4. The second pushing device 6 drives the baffle 10 to pass through the notch 11 to squeeze the side of the lining block, so that the two small lining blocks that make up the lining block are aligned. Preferably, the second pushing device 6 drives the second push plate 9 and the baffle 10 to move at the same time. When the baffle 10 squeezes the side of the lining block, the second push plate 9 is close to the discharge port 4 and is located on one side of the discharge port 4. When the lining block passes through the discharge port 4 and enters the crown wheel groove 8, the second push plate 9 pushes the lining block away from the discharge port 4. When the liner passes through the gap 11, the second pushing device 6 drives the baffle 10 close to the liner and squeezes the side of the liner to ensure that the two small liner blocks are aligned when entering the sheave liner, ensuring that the liner installation meets the requirements. At this time, the second push plate 9 driven by the second pushing device 6 is close to the discharge port 4 and is located on one side of the discharge port 4. When the liner enters the sheave groove 8, the second pushing device 6 drives the baffle 10 away from the exit gap 11, the second push plate 9 is away from the discharge port 4, and can push the liner away from the discharge port 4, leaving space for the next liner block to enter the sheave groove 8.

[0028] Preferably, the first pushing device 5 is fixedly connected to the housing 1 by screws, and the second pushing device 6 is fixedly connected to the housing 1 by screws.

[0029] Preferably, the baffle 10 and the second push plate 9 are integrally formed. Preferably, the integral part formed by the baffle 10 and the second push plate 9 is a sheet metal part, which is provided with a through hole, and the sheet metal part and the second push device 6 are fixed by screws.

[0030] Preferably, the height of the cavity 2 matches the height of the lining block, and the two are clearance-fitted.

[0031] Preferably, the first pushing device 5 is a cylinder.

[0032] Preferably, the second pushing device 6 is a cylinder.

[0033] Preferably, the housing 1 is fixedly connected to the side wall of the sheave via fasteners, and the fasteners can be screws or bolts.

[0034] Preferably, the first pushing device 5 and the second pushing device 6 are both connected to the housing 1 by screws.

[0035] Preferably, the cavity (2) and the lining block are clearance-fitted. Since a certain gap must be left between the lining block and the cavity 2 so that the lining block can be smoothly pushed by the first push plate and prevent the lining block from getting stuck in the cavity 2, the sides of the two small lining blocks that make up the lining block may be misaligned. The setting of the baffle 10 can squeeze and align the lining block before entering the sheave groove 8, thereby ensuring that the two small lining blocks that make up the lining block can be aligned and smoothly enter the sheave groove 8. After entering the sheave groove 8, the two small lining blocks will not become loose due to the structural restriction of the sheave groove 8. Therefore, the second push plate 9 squeezes and aligns the two small lining blocks to meet the installation requirements. As for the lining block and the cavity in the vertical direction, they are also clearance-fitted and may also be misaligned. However, under the influence of gravity, the two small lining blocks that make up the lining block will automatically align with each other in the vertical direction without being subjected to a sudden increase in external force.

[0036] like Figure 3 and Figure 4 As shown, Figure 3 This is a reference diagram of the state when the second pushing device 6 is contracted. Figure 4 The reference figure is the state when the second pushing device 6 is extended. When in use, the cavity 2 in the shell 1 matches the size of the liner block, and the liner block is placed in the cavity 2 through the feed port 3. The first push plate 7 is driven by the first pushing device 5 to make the liner block move in the cavity 2. When the liner block passes through the discharge port 4, it will enter the groove from the groove on the side of the sheave. Since the liner block moves completely in the cavity 2 during the assembly process, and the internal space of the cavity 2 is the same size as the liner block, the two small liner blocks will not be scattered during the movement of the liner block in the cavity 2 until they enter the sheave groove 8, thereby realizing the installation of the liner block. Compared with traditional technology, this technical solution only needs to put the two spliced ​​small liner blocks into the feed port 3 as a complete liner block. How the liner block accurately enters the sheave groove 8 is automatically completed by the equipment, which replaces the process of using tools to press or knock on the liner block. It also ensures that the two small liner blocks are aligned and fit tightly, meeting quality requirements, making the installation of the liner block time-saving and labor-saving.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. That is, any equivalent changes and modifications made according to the content of the patent application of the present invention should fall within the technical scope of the present invention.
