Abstract
The rail joint connection clamp comprises two clamping blocks which are arranged in bilateral symmetry, bayonets with opposite opening directions are arranged on the two clamping blocks, the bayonets are wedge-shaped, the bayonets are wide outside and narrow inside, the distance between the bayonets and the top surface of the clamped rail is more than or equal to 20mm, and fixing bolts are connected between the two clamping blocks. The height of the device is reduced, and on the basis of ensuring the strength of a connecting structure at the joint of the rails, a passing space is provided for auxiliary wheels and braking devices on the mining man car, so that the mining man car is ensured to pass safely and smoothly.
Description
Technical Field
The utility model relates to a connect the connecting piece at mining rail seam, especially relate to a rail seam joining anchor clamps.
Background
In the process of laying mine rails, because two adjacent rails have joints in the butt joint process, in order to ensure the structural stability of the installation of the two rails, connecting pieces are required to be connected between the two butted rails. The existing rail joint connecting piece is mainly composed of connecting plates fixedly installed on vertical surfaces of two sides of two rails through bolts, the rail joint connecting piece is high in height, auxiliary wheels and braking devices supported on vertical surfaces of the outer sides of the rails are installed on two sides of a mining man car, the rail joint connecting piece with high height influences the passing of the mining man car, the connecting plates are installed only on the vertical surfaces of the inner sides of the rails in the existing mode, the mode of adopting the single-side connecting plates is low in connecting strength, the connecting structure of the rail joints is not firm, and potential safety hazards exist in the passing of the mining man car.
Disclosure of Invention
The utility model provides a solve above-mentioned technical problem, provide a rail seam connection anchor clamps, it has reduced self height, on the basis of guaranteeing rail seam crossing connection structure intensity, provides current space for auxiliary wheel and arresting gear on the mining people's car, guarantees that mining people's car is safe current smoothly.
On the basis of ensuring the firm connection structure of the rail joint,
the technical solution of the utility model is that:
the rail joint connecting clamp is characterized in that: the clamping device comprises two clamping blocks which are arranged in bilateral symmetry, bayonets with opposite opening directions are arranged on the two clamping blocks, the bayonets are wedge-shaped, the bayonets are wide outside and narrow inside, the distance between the bayonets and the top surface of a clamped rail and the top surface of the clamped rail is more than or equal to 20mm, and fixing bolts are connected between the two clamping blocks.
Further preferably, the fixing bolt connected between the two clamping blocks is positioned below the bayonet.
Further preferably, the fixing bolt connected between the two clamping blocks is positioned above the bayonet.
Further preferably, the outer sides of the two clamping blocks are respectively provided with a fixing plate, vertical foundation bolts are installed on the fixing plates, the clamping blocks are fixed with the ground through the foundation bolts, and stability of the clamping block installation structure is improved.
The utility model has the advantages that:
the clamping blocks are symmetrically arranged at the left and right sides, the bayonets are arranged on the two clamping blocks, the openings of the bayonets are opposite, the bayonets are wedge-shaped, the bayonets are wide outside and narrow inside, the distance between the top surfaces of the clamping blocks and the inner top surface of the rail after the clamping of the rail is more than or equal to 20mm, and the fixing bolts are connected between the two clamping blocks, so that the height of the fixing bolts is reduced, on the basis of ensuring the strength of a connecting structure at the joint of the rail, a passing space is provided for auxiliary wheels and a braking device on the mining man car.
Drawings
Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention;
fig. 2 is a schematic structural diagram of embodiment 2 of the present invention;
in the figure: 1-clamping block, 2-bayonet, 3-fixing bolt, 4-fixing plate and 5-foundation bolt.
Detailed Description
Example 1
As shown in figure 1, the rail joint connection clamp comprises two clamping blocks 1 which are arranged in bilateral symmetry, bayonets 2 with opposite opening directions are arranged on the two clamping blocks 1, the bayonets 2 are wedge-shaped, the outer width of the bayonets 2 is small, fixing bolts 3 are connected between the two clamping blocks 1 and below the bayonets 2, fixing plates 4 are respectively arranged on the outer sides of the two clamping blocks 1, vertical foundation bolts 5 are mounted on the fixing plates 4, and the distance between the fixing plates and the top surface of the clamped rail 1 and the inner top surface of the rail is more than or equal to 25 mm.
When the device is installed, the bayonets 2 of the two clamping blocks 1 are inserted and buckled on the left side and the right side of the bottom surfaces of the two rails butted at the joint, then the fixing bolts 3 are fastened, and finally the foundation bolts 5 are fixedly installed underground to finish the operation.
Example 2
As shown in fig. 2, the rail joint connection clamp comprises two clamping blocks 1 which are arranged in bilateral symmetry, bayonets 2 with opposite opening directions are arranged on the two clamping blocks 1, the bayonets 2 are wedge-shaped, the bayonets 2 are wide outside and narrow inside, a fixing bolt 3 is connected between the two clamping blocks 1 and above the bayonets 2, fixing plates 4 are respectively arranged on the outer sides of the two clamping blocks 1, vertical foundation bolts 5 are mounted on the fixing plates 4, and the distance between the fixing plates and the top surface of the clamping block 1 after the clamping of a rail is more than or equal to 20mm from the inner top surface of the rail.
When the device is installed, the bayonets 2 of the two clamping blocks 1 are inserted and buckled on the left side and the right side of the bottom surfaces of the two butted rails at the joint, then through holes corresponding to the fixing bolts 3 are formed in the two butted rail vertical surfaces, the fixing bolts 3 penetrate through the through holes formed in the two clamping blocks 1 and the rail vertical surfaces and are fastened, and finally the foundation bolts 5 are fixedly installed underground to finish the operation.
The above description is only an example of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
