Description

TECHNICAL FIELD

[0001] The utility model relates to a pick disc auxiliary support technical field, specifically a pick disc auxiliary support frame. BACKGROUND

[0002] In many fields such as modern engineering construction and mining, pick discs play a very key role. As the core component of excavating and cutting equipment, pick discs are complex and precise in structure, usually composed of multiple picks evenly distributed on the disc body, used for direct contact with hard materials such as rocks and ores and for breaking operations.

[0003] With the continuous development of related industries, the requirements for the production, installation, debugging, maintenance and transportation of pick discs are increasing. In the production process of pick discs, from part processing to final assembly, pick discs need to be transferred and operated between multiple processes. The traditional handling method often relies on simple lifting equipment and manual assistance. Due to the large weight and irregular shape of pick discs, the picks on the surface of the pick disc are easily damaged or the disc body structure is deformed during handling due to uneven stress, affecting the subsequent performance and service life.

[0004] During installation and debugging, pick discs need to be precisely connected and fixed with the main equipment. However, due to the lack of a special auxiliary support device, it is difficult to maintain a stable posture and accurate position of the pick disc during installation, which not only increases the difficulty and time cost of installation, but also easily leads to a decline in the overall performance of the equipment due to installation errors, and even causes safety accidents. For example, in the installation of the pick disc of a tunnel boring machine, if the installation position of the pick disc deviates too much, it will cause uneven distribution of cutting force, accelerate pick wear, reduce the efficiency of excavation, and also bring additional load and wear to the transmission system of the equipment.

[0005] In terms of transportation and storage, due to the large size and heavy weight of pick discs, the conventional stacking method is easy to cause pick discs to be pressed and collided with each other, causing damage to picks and deformation of the disc body. Moreover, during transportation, the bumps and vibrations of the vehicle will further increase the risk of damage to the pick disc. If these problems cannot be effectively solved, not only will the maintenance cost of the pick disc increase significantly, but also the pick disc will need to be replaced frequently, affecting the progress of the project and the production efficiency. Therefore, we provide a pick disc auxiliary support frame to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0027] As shown in Figures 1-5 The utility model provides a technical scheme: a pick disc 4 auxiliary support frame, including base 1 and movable plate 3, the front end of base 1 and the lower end between movable plate 3 are established movable connection relation through support column 17, support column 17 is evenly distributed between both, material selection uses high-strength alloy steel, has outstanding compression and bending resistance, and movable connection is realized with the help of pin shaft between support column 17, this makes movable plate 3 can be flexibly adjusted in angle relative to base 1, adapts to different work requirements and working conditions.

[0028] As shown in Figure 4 Between base 1 and movable plate 3, hydraulic telescopic rod 16 is installed, and the two ends of hydraulic telescopic rod 16 are fixed with fixed blocks 15. The fixed blocks 15 at the upper and lower ends are fixedly connected with movable plate 3 and base 1 by pin shafts. The design of hydraulic telescopic rod 16 can adjust the angle of movable plate 3, which is convenient for placing pick disc 4 on movable plate 3, and is also convenient for rotating pick disc 4 when movable plate 3 is horizontal and installing pick tooth head in positioning hole 5. The hydraulic telescopic rod 16 can stably fold and open the movable plate 3, and can be reliably locked at any position, which is convenient for installing pick disc 4 later.

[0029] As shown in Figure 3 A groove 7 is symmetrically formed at the center position of movable plate 3, and a bearing 8 is installed in the groove 7. The bearing 8 is a ball bearing 8 or a needle bearing 8, which has the characteristics of low friction, high speed and long service life, and can ensure smooth rotation of the shaft 9 passing through it. Threaded rods 10 are fixed between the opposite surfaces of the shaft 9. The threaded rods 10 are threadedly connected with support blocks 11. By using threaded connection, the friction force can be increased to ensure the stability of the support;

[0030] At the same time, limit grooves 18 are symmetrically formed in the groove 7. The limit grooves 18 cooperate with limit blocks 19 fixed on the surface of the support blocks 11. The limit blocks 19 can freely slide in the limit grooves 18, which can limit the rotational freedom of the support blocks 11, so that the support blocks 11 can only move linearly along the threaded rods 10. Therefore, when the motor 14 drives the shaft 9 and the threaded rods 10 to rotate, the support blocks 11 can accurately move towards or away from the inner wall of the pick disc 4, realizing accurate support and release of the pick disc 4;

[0031] A driven wheel 13 is fixed on the surface of the rotating shaft 9 near the center of the movable plate 3, and a motor 14 is fixed on the back surface of the movable plate 3 at the center position, and the output shaft of the motor 14 penetrates through the movable plate 3 and is fixed with a driving wheel 6 at the front end of the movable plate 3, and the driving wheel 6 is in meshing relationship with the uniformly distributed driven wheels 13, forming a reliable gear transmission system, which can stably transmit the power of the motor 14 to each rotating shaft 9 and threaded rod 10, and further drive the support block 11 to work cooperatively.

[0032] Specifically, as shown in Figure 3 The surface of the movable plate 3 is provided with an area specially used for placing the cutting tooth disc 4, and the area is uniformly arranged with guide wheels 12 made of wear-resistant and elastic materials such as nylon or rubber-coated metal hubs. The surface of the guide wheel 12 is in lap joint with the cutting tooth disc 4. When the cutting tooth disc 4 is placed on the movable plate 3, the guide wheel 12 can play a role in auxiliary support and guidance, greatly reducing the frictional resistance between the cutting tooth disc 4 and the movable plate 3, making the cutting tooth disc 4 more convenient in placing and adjusting position. At the same time, since the guide wheels 12 are uniformly arranged at the center of the movable plate 3, the placement position of the cutting tooth disc 4 on the movable plate 3 can be relatively accurately and stably ensured, providing a good foundation for subsequent support operation.

[0033] Specifically, when the cutting tooth disc 4 is placed on the movable plate 3, the inner wall thereof is in lap joint with the surface of the support block 11, and the surface of the cutting tooth disc 4 is further provided with a positioning hole 5, which facilitates the installation of the cutting tooth head in the positioning hole 5. The rear end surface of the base 1 is fixed with a support table 2. When the movable plate 3 is flat, the bottom end of the movable plate 3 is in lap joint with the surface of the support table 2, and the design height of the support table 2 matches the flat position of the movable plate 3, which can provide additional support force for the movable plate 3 and enhance the stability of the entire support frame in the non-working state or transportation process. In the transportation process, the close lap joint of the support table 2 and the movable plate 3 can effectively prevent the movable plate 3 from shaking due to vehicle bumping and protect the cutting tooth disc 4 from being damaged; in the storage state, the support table 2 also helps to maintain the horizontal state of the movable plate 3, avoiding deformation or sinking of the movable plate 3 due to long-term placement.
