Description

Technical Field

[0001] The utility model belongs to the technical field related to mining support, and particularly relates to a gangway anchor cable support clamping device. Background Art

[0002] Anchor cable is a prestressed element used in civil engineering to enhance the stability of slopes, bridges, tunnels and other structures. It is usually made of high-strength steel strands, and the prestress is transmitted through the anchoring system at both ends to resist displacement or damage caused by external forces. Anchor cables can be used alone or in combination with other support structures, such as anchor rods and soil nails, to improve overall stability and safety. During the support process, when mining and tunnel repair are setting the auxiliary anchor cables (anchor rods), construction workers usually need to hold the drill rod by hand to point and position, but it still has the following disadvantages in actual use:

[0003] When the drill rod rotates at high speed, a large amount of water and mud will gush out from the borehole, making the surface of the drill rod extremely slippery. In such a working environment, the hands of construction workers are easily scratched or even caught by the slippery drill rod, especially when they hold the drill rod with gloves or sleeves of work clothes not fastened, the risk of fingers being caught increases exponentially;

[0004] When the clamping device is in the process of holding or transporting, the two clamping structures become loose, which may easily cause people's hands to be clamped when holding, posing certain safety hazards and making holding and transporting inconvenient. Utility Model Content

[0005] The purpose of the utility model is to provide a supporting clamping device for the side anchor cable. By arranging a rotating arm, a rotating assembly, an arc-shaped clamping plate, a return spring and a handle, the problem that when the drill bit is in operation, the hand contact and adjustment is easily scratched or even entangled by the slippery drill rod, causing a safety hazard, and the hand is easily clamped when holding the transport clamping device is solved.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a gang anchor cable supporting and clamping device, comprising a swivel arm, a swivel assembly, an arc-shaped clamping plate, a return spring and a handle, the swivel assembly comprises a connecting shaft, the circumferential side of the connecting shaft is rotatably connected to two swivel arms, the two swivel arms are symmetrically arranged in a side view, a connecting arm is fixed at one end of the swivel arm, an arc-shaped clamping plate is arranged on the side where the two connecting arms are close to each other, a return spring is arranged on the side of the connecting shaft away from the arc-shaped clamping plate, and a handle is fixed at one end of the two swivel arms away from the connecting arm. When working, the two swivel arms are connected together through the swivel assembly, and the power of the handle during rotation is transmitted by the swivel arm to clamp the drill rod through the arc-shaped clamping plate, and the swivel arm is reset after the handle is released through the return spring, and the swivel arm is held well by the grip of the handle.

[0008] Furthermore, the rotating arms are provided with rotating holes corresponding to the positions of the connecting shafts, the connecting shaft is movably connected to the rotating holes on the two rotating arms, and the rotating arms are movably connected to the connecting shafts through the rotating holes.

[0009] Furthermore, the rotating assembly also includes a limit block, and the limit blocks are fixed at both ends of the connecting shaft. The limit blocks are arranged on the side where the two rotating arms are away from each other, and the rotating assembly limits the positions of the two rotating arms through the limit blocks.

[0010] Furthermore, the end face of the arc-shaped clamping plate is set in a minor arc, and a connecting column is fixed on the arc-shaped outer surface of the arc-shaped clamping plate. The connecting column is fixed on the side where the two connecting arms are close to each other, and is set at the edge of the side where the two connecting arms are close to each other and away from the rotating arm. A number of friction sleeves are evenly fixed on the inner wall of the arc-shaped clamping plate, and the arc-shaped clamping plate increases the friction force between the drill rod and the arc-shaped clamping plate through the friction sleeves.

[0011] Furthermore, connecting rods are fixed at both ends of the return spring, and fixed blocks are fixed at one end of the two connecting rods away from the return spring. The two fixed blocks are respectively fixed on the two rotating arms, and the return spring is connected to the two rotating arms through the fixed blocks connected by the connecting rods to limit the position on the two rotating arms.

[0012] Furthermore, a gripping sponge cover is fixed to the sides of the two grips that are away from each other, and a reinforcing rib is fixed to the sides of the two grips that are close to each other. The reinforcing rib is fixed to the end of the rotating arm, and the gripping sponge cover increases the comfort of holding the grip.

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

[0014] The utility model solves the problem that when the drill bit is in operation, the hands are easily scratched or even entangled by the slippery drill rod when adjusting the drill bit, thus causing safety hazards by arranging a rotating arm, a rotating assembly and an arc-shaped clamping plate. By holding the two handles, the two arc-shaped clamping plates are arranged on the outside of the drill rod, and the rotating arm is rotated to make the arc-shaped clamping plates connected by the two connecting arms approach each other. After the arc-shaped clamping plates are clamped, the operator does not need to touch the drill rod, and it is safer to adjust the position of the drill rod.

[0015] The utility model solves the problem that the hands are easily clamped when holding the transfer clamping device by arranging a rotating arm, a return spring and a handle. The operator holds the handle with both hands, and the comfort of holding is increased by holding the sponge cover when holding the handle. When the work is completed, the return spring maintains the angle between the rotating arms during operation to prevent the operator's skin from being clamped between the two arc-shaped clamping plates when taking the rotating arm, thereby increasing the safety of taking the rotating arm.
