Description

Technical Field

[0001] This utility model belongs to the field of crane-related technical technology, and in particular relates to a track pressure plate that assists in the rotation of a crane. Background Technology

[0002] Crane rail clamps are key components used to secure crane rails. Their main functions include preventing rail displacement, distributing loads, adjusting rail position, and damping shocks. They firmly press the rails to the concrete beam or metal structure foundation using bolts or other fastening methods, ensuring the stability and safety of the crane during operation. Depending on different usage requirements, rail clamps can be divided into various types, such as ordinary clamps, elastic clamps, adjustable clamps, and welded clamps, suitable for different loads and environmental conditions. However, crane rail clamps still have the following drawbacks in practical use:

[0003] During use, the crane rail pressure plate is directly installed using installation equipment. After installation, it is used to assist in the installation of the crane. However, during crane operation, some parts need to be rotated. When the crane needs to rotate, it will cause a torsional effect on the rail, causing the rail to deviate and affecting the operating stability of the crane.

[0004] Secondly, during operation, the crane rail plate requires the use of screws and nuts to install the crane rail plate on the base. However, as the operation progresses, the vibration of the crane on the rail can cause the nuts of the plate to loosen. Utility Model Content

[0005] The purpose of this utility model is to provide a track pressure plate that assists in the rotation of a crane. By setting up an installation base, an installation track, a pressure plate body and an elastic gasket, it solves the problem that the crane track pressure plate is prone to track displacement when facing the crane and rotation operation, and that the nuts are prone to loosening after long-term use.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a track pressure plate for assisting crane rotation, comprising a mounting base, a mounting rail, a pressure plate body, and elastic gaskets. The mounting base has a mounting rail on its top, and pressure plate bodies are mounted on the top of the mounting base on both sides of the mounting rail. The pressure plate bodies are secured to the bottom of the mounting rail on both sides. Mounting blocks are fixed at the two corners of the lower part of the pressure plate body away from the mounting rail. An elastic gasket is mounted on the top of each pressure plate body. The mounting base serves as a foundation support, and the mounting rail is mounted on top for the crane to move. The pressure plate bodies on both sides of the rail secure the bottom of the rail, limiting its lateral displacement. The mounting blocks on the outer side of the pressure plate body cooperate with the elastic gaskets to enhance torsional resistance and provide elastic preload, respectively, ensuring rail stability.

[0008] Furthermore, mounting screws are fixed to the top of the mounting bases on both sides of the mounting track. A clamping nut is threaded to the upper part of the circumference of the mounting screw. The mounting screw is vertically fixed to the top of the base. The clamping nut locks the pressure plate body and the elastic washer, forming an adjustable rigid connection structure.

[0009] Furthermore, both pressure plate bodies have fitting grooves at the bottom near the edge of the mounting track. The two sides of the mounting track bottom are movably connected in the fitting grooves. The fitting grooves at the bottom of the pressure plate bodies engage with the two sides of the track bottom to prevent longitudinal movement of the track, while allowing slight deformation to mitigate impact.

[0010] Furthermore, a vertical through-hole is provided inside the pressure plate body, through which the mounting screw passes. The mounting screw is fitted into the mounting hole of the pressure plate body, which not only fixes the position of the pressure plate but also provides an axial channel for the nut to be tightened.

[0011] Furthermore, each of the mounting blocks has a pin vertically inserted through it, and the top of the mounting base has a through hole corresponding to the four pin positions. All the pins pass through the mounting blocks and are inserted into the holes respectively. Each pin has a connector fixed at its top. The pins pass through the holes on the mounting blocks and the base to form a triangular anti-torsion structure, which disperses the lateral load when the crane turns and reduces the risk of track deviation.

[0012] Furthermore, a hollow groove is formed through the bottom of the elastic gasket, and a fixing hole is formed vertically through the center of the elastic gasket. The mounting screw passes through the mounting hole and extends out of the elastic gasket. The clamping nut abuts against the top of the elastic gasket. The elastic gasket is deformed by pressure through the hollow groove to generate a rebound force, which compensates for the loosening of the clamping nut. The fixing hole ensures that the gasket and the screw are aligned, so that the pressure is evenly transmitted to the pressure plate body.

[0013] This utility model has the following beneficial effects:

[0014] This utility model solves the problem of track displacement caused by the crane track pressure plate when facing the crane for rotational operation by setting up an installation base, installation track, and pressure plate body. When the crane runs and rotates on the installation track, the installation screw is set in the pressure plate body, and the pin is locked in the insertion hole in the installation block and the installation base on the pressure plate body, so that a triangular installation force point is formed on the same pressure plate body, which reduces the displacement of the installation track during crane rotation and increases the installation stability of the installation track.

[0015] This utility model solves the problem of nuts easily loosening due to long-term use of crane rail pressure plates by setting up an installation base, installation rail, pressure plate body, and elastic gasket. The hollow groove at the bottom of the elastic gasket is set downwards. After the installation screw is put into the installation hole extending from the top of the pressure plate body, the clamping nut is screwed onto the installation screw and pressed between it and the elastic gasket. After the elastic gasket is elastically deformed, it is completely compressed. The elasticity of the elastic gasket compensates for the loosening of the clamping nut during continuous operation, ensuring a tight installation between the installation base and the pressure plate body, and ensuring the installation stability of the installation rail.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-4 This utility model is a track pressure plate for assisting the rotation of a crane, including a mounting base 1, a mounting rail 2, a pressure plate body 3, and elastic pads 4. The mounting base 1 has a mounting rail 2 on its top, supporting the mounting rail 2 and providing the crane's movement. The mounting base 1 has a pressure plate body 3 on the top of the mounting base 1 on both sides of the mounting rail 2. During operation, the pressure plate body 3 presses against the mounting rail 2, locking the mounting rail 2 on both sides of the rail bottom, thus fixing the position of the mounting rail 2 on the mounting base 1 during operation. At the two corners of the lower part of the pressure plate body 3 away from the mounting rail 2, mounting blocks 303 are fixed. The mounting blocks 303, together with pins 304, restrict the pressure plate body 3 and the mounting base 1, reducing the installation position displacement caused by the torsion of the mounting rail 2 during crane rotation. Each pressure plate body 3 has an elastic pad 4 on its top, which supports the pressure plate body 3.

[0026] Specifically, mounting screws 102 are fixed to the top of the mounting bases 1 on both sides of the mounting track 2. A clamping nut 103 is threaded to the upper part of the circumference of the mounting screw 102. The mounting track 2 is used to install the pressure plate body 3 through the mounting screws 102. The clamping nut 103 is used to install the pressure plate body 3 and the elastic gasket 4.

[0027] Furthermore, both pressure plate bodies 3 have fitting grooves 302 at the bottom near the edge of the mounting rail 2. The two sides of the bottom of the mounting rail 2 are movably connected in the fitting grooves 302. The pressure plate bodies 3 are fitted onto the mounting rail 2 through the fitting grooves 302, so that the mounting rail 2 is restricted to the mounting base 1.

[0028] Furthermore, a vertical through-hole 301 is provided inside the pressure plate body 3, and a mounting screw 102 passes through the mounting hole 301. The mounting screw 102 is movably set in the pressure plate body 3 through the mounting hole 301, thereby restricting and defining the mounting track 2 and the pressure plate body 3.

[0029] Furthermore, each mounting block 303 has a vertically inserted pin 304. The top of the mounting base 1 has a through hole 101 corresponding to the positions of the four pins 304. After all the pins 304 pass through the mounting block 303, they are inserted into the through hole 101 respectively. The top of each pin 304 is fixed with a connector 305. After the mounting block 303 is inserted through the pin 304, it is then inserted into the through hole 101 on the mounting base 1, so that the position between the mounting base 1 and the pressure plate body 3 is further restricted.

[0030] The operation process of this embodiment is as follows: First, after placing the mounting base 1 at the position where the mounting track 2 needs to be set, the mounting base 1 is installed on the ground using expansion bolts, etc. The mounting track 2 is placed on the mounting base 1. Then, the fitting groove 302 at the bottom of the pressure plate body 3 is engaged with the bottom of the mounting track 2. Simultaneously, the mounting screw 102 passes through the mounting hole 301 of the pressure plate body 3 and extends out of the pressure plate body 3. Next, the hollow groove 402 of the elastic washer 4 is set downwards, and the fixing hole 401 is fitted onto the mounting screw 102. After the mounting block 303 is placed on the mounting base 1, then… Insert the pin 304 into the mounting block 303 and into the insertion hole 101 on the mounting base 1. Then screw the clamping nut 103 onto the mounting screw 102 and rotate it to press it against the elastic washer 4. When the crane runs and rotates on the mounting rail 2, the pin 304 is locked in the mounting block 303 and the insertion hole 101 on the mounting base 1 through the mounting screw 102 set in the pressure plate body 3, so that a triangular installation force point is formed on the same pressure plate body 3, reducing the offset of the mounting rail 2 during the rotation of the crane and increasing the installation stability of the mounting rail 2. Specific Implementation Example 2

[0031] Please see Figure 1-5 Based on the first specific embodiment, a hollow groove 402 is provided through the bottom of the elastic gasket 4, and a fixing hole 401 is provided vertically through the center of the elastic gasket 4. The mounting screw 102 passes through the mounting hole 301, passes through the fixing hole 401, and extends out of the elastic gasket 4. The clamping nut 103 abuts against the top of the elastic gasket 4. The elastic gasket 4 provides elastic deformation of the clamping nut 103 during installation through the hollow groove 402, and is movably connected to the mounting screw 102 through the fixing hole 401. When the clamping nut 103 is squeezed, it provides elastic rebound, so that the pressure plate body 3 and the mounting base 1 are locked together.

[0032] The operation process of this embodiment is as follows: During the installation process, the hollow groove 402 at the bottom of the elastic gasket 4 is directly set downwards. After the mounting screw 102 is put into the mounting hole 301 extending from the top of the pressure plate body 3, the clamping nut 103 is screwed onto the mounting screw 102 and pressed between it and the elastic gasket 4. After the elastic gasket 4 is elastically deformed, the elastic gasket 4 is completely compressed. Through the elasticity of the elastic gasket 4, the loosening of the clamping nut 103 during continuous operation is compensated, ensuring that the mounting base 1 and the pressure plate body 3 are installed firmly and ensuring the installation stability of the mounting track 2.
