Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to the technical field of single-track crane beam track jointing, and specifically refers to a single-track crane beam track jointing device. Background Technique

[0002] When installing the track, the length of the track at the splicing position is usually 20-30 mm shorter than the actual length of the track to be spliced. Equipment is needed to tow the tracks at both ends of the splicing position towards the middle to achieve track splicing. This process of track splicing is called track jointing. The track splicing position is called the position to be jointed, and the tracks at both ends of the splicing are called jointed tracks. The traditional track jointing method is to use a chain block to tow the two ends of the track beam of the jointed track for the installation of the jointed track. This method has the following disadvantages: First, during the installation construction of the single-track crane beam track in the past, the installation of the jointed track required 3 people to cooperate with the chain block for 1-1.5 hours. The time required to install one jointed track is more than three times the time required to install a normal track, seriously affecting the track installation efficiency. Second, when using a chain block to tow the beam for track jointing installation, the round-link chain needs to be tied to the beam of the jointed track at both ends of the position to be jointed first, and then the chain block is used to hang on the round-link chains at both ends and tow towards the middle to achieve track jointing. This operation process is cumbersome, the workload of personnel is large, and personnel need to perform high-altitude operations to tie the round-link chain, which poses a certain safety risk. In addition, the chain block can generally only be hung on the side of the beam of the jointed track. During the towing process, due to reasons such as operation tools and operation methods, it is easy to cause misalignment of the jointed tracks at both ends, resulting in difficult track installation. Therefore, there is a need for a single-track crane beam track jointing device that can perform jointing safely, quickly, and effectively. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a single-track crane beam track jointing device to solve the problems of low installation efficiency, high installation risk, difficult installation, and easy misalignment of the jointed track during the installation process of the jointed track in the prior art.

[0004] To achieve the above purpose, the utility model provides a single-track crane beam track jointing device, which includes a claw, a stud traction assembly, a traction chain, and a rotating mechanism. The claw includes a first claw and a second claw. The first claw is installed on the jointed track on one side of the position to be jointed, and the second claw is installed on the jointed track on the other side of the position to be jointed. One side of the stud traction assembly is connected to the first claw, and the other side is connected to the second claw through the traction chain. The rotating mechanism includes a ratchet wheel, a handle, and a pawl. The ratchet wheel is fixed at one end of the stud traction assembly, one end of the handle is sleeved on the ratchet wheel, and the pawl is arranged at the connection between the handle and the ratchet wheel.

[0005] Further, the first jaw includes a first clamping piece, a second clamping piece and a bolt. The first clamping piece and the second clamping piece have exactly the same structure, including a clamping part, a bending part and a fixing part. The clamping part and the fixing part are kept parallel, and the bending part is perpendicular to the clamping part. The clamping parts of the first clamping piece and the second clamping piece are parallel and relatively clamped on the butting track. The fixing parts of the first clamping piece and the second clamping piece are fixed and disassembled by bolts.

[0006] Further, the second jaw has exactly the same structure as the first jaw.

[0007] Further, the wire-aligning traction assembly includes a wire-aligning interface, a first wire-aligning pull rod and a second wire-aligning pull rod. The wire-aligning interface is an external joint with internal threads engraved on both sides. The first wire-aligning pull rod and the second wire-aligning pull rod are screw rods with a connecting ring at one end. The screw rods are threadedly connected to the corresponding joints on both sides of the wire-aligning interface. The connecting ring of the first wire-aligning pull rod is nested on the bolt of the first jaw, and the connecting ring of the second wire-aligning pull rod is rotatably connected to the traction chain.

[0008] Further, the traction chain is a metal chain, and the traction chain is nested on the bolt of the second jaw through a connecting ring.

[0009] Further, the ratchet is a gear with a rigid tooth-shaped surface on the outer edge, and is axially fixed on the joint on one side of the wire-aligning interface.

[0010] Further, the handle is Y-shaped, and the open end is sleeved on both sides of the ratchet.

[0011] Further, the pawl is a metal stop piece. One end of the pawl is fixedly connected to the middle of the two forks of the handle, and the other end meshes with the ratchet.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, the jaw is fixed to the bottom of the butting track by bolts, instead of the traditional way of fixing the track side by a manual chain hoist, which avoids the situation of misalignment of the butting track during installation due to pulling the track side. At the same time, the jaw and the butting track are fixed by bolts, which is convenient for disassembly and installation; by repeatedly rotating the handle, the handle drives the ratchet and the wire-aligning to rotate, and then drives the first wire-aligning pull rod and the second wire-aligning pull rod to retract inward, realizing the installation of the butting track, making the installation of the butting track more convenient and labor-saving, and doubling the installation efficiency of the butting track; by applying a rotational force to the handle, workers can perform the operation of installing the butting track on the ground, avoiding high-altitude operation of personnel and ensuring the safety of workers during operation; in the present utility model, the second jaw and the second wire-aligning pull rod are connected by a traction chain, and a traction chain with a suitable length can be selected according to the distance between the butting tracks on both sides of the position to be butted, which has general adaptability.

[0020] The following will clearly and completely describe the technical solutions of the present utility model in conjunction with the drawings. Obviously, the described embodiments are some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Such as Figure 1 , Figure 2 And Figure 3The shown monorail crane beam rail jointing device includes a claw 1, a screw traction assembly 2, a traction chain 3 and a rotating mechanism 4. The claw 1 includes a first claw 11 and a second claw 12. The first claw 11 is installed on the jointing rail 5 on one side of the position to be jointed, and the second claw 12 is installed on the jointing rail 5 on the other side of the position to be jointed. One side of the screw traction assembly 2 is connected to the first claw 11, and the other side is connected to the second claw 12 through the traction chain 3. The rotating mechanism 4 includes a ratchet 41, a handle 42 and a pawl 43. The ratchet 41 is fixed at one end of the screw traction assembly 2, one end of the handle 42 is sleeved on the ratchet 41, and the pawl 43 is arranged at the connection between the handle 42 and the ratchet 41. By repeatedly rotating the handle 42 to drive the ratchet 41 to rotate, the screw traction assembly 2 is driven to contract inward.

[0022] Specifically, the structures of the second claw 11 and the first claw 12 are exactly the same. Taking the first claw 11 as an example, it includes a first clamping piece 111, a second clamping piece 112 and a bolt 113. The first clamping piece 111 and the second clamping piece 112 have exactly the same structure, including a clamping part, a bending part and a fixing part. The clamping part and the fixing part are kept parallel, and the bending part is perpendicular to the clamping part. The clamping parts of the first clamping piece 111 and the second clamping piece 112 are parallel and relatively clamp the jointing rail 5. The fixing parts of the first clamping piece 111 and the second clamping piece 112 are fixed and disassembled through the bolt 113. The first clamping piece 111 and the second clamping piece 112 are fixedly clamped on both sides of the jointing rail 5 through the bolt 113, and the bending part is in parallel contact with the bottom of the jointing rail. When the screw traction assembly 2 contracts inward, it drives the first claw 11 and the second claw 12 to move closer inward, and then drives the jointing rails 5 fixed by the claw 1 to move closer to each other.

[0023] Specifically, the screw traction assembly 2 includes a screw interface 22, a first screw pull rod 21 and a second screw pull rod 23. The screw interface 22 is an external joint with internal threads engraved on both sides. The first screw pull rod 21 and the second screw pull rod 23 are screw rods with connecting rings at one end. The screw rods are threadedly connected to the corresponding joints on both sides of the screw interface 22. The connecting ring of the first screw pull rod 21 is nested on the bolt of the first claw 11, and the connecting ring of the second screw pull rod 23 is rotatably connected to the traction chain 3. The joints on both sides of the screw interface 22 have exactly the same structure. The screw rods of the first screw pull rod 21 and the second screw pull rod 23 are threadedly arranged on the corresponding joints of the screw interface. The rotation of the screw interface 22 drives the first pull rod 21 and the second pull rod 23 to move closer, so that the screw traction assembly 2 contracts inward, and the jointing rails fixed by the first claw 11 and the second claw 12 are driven to move closer.

[0024] Specifically, the traction chain 3 is a metal chain, and the traction chain 3 is nested on the bolt of the second claw 12 through a connecting ring. During the installation of the single-track crane beam track splicing device, the length of the traction chain 3 is adjusted according to the distance between the splicing tracks on both sides of the required splicing position, so that it is in a tensioned state during operation.

[0025] Specifically, the ratchet wheel 41 is a gear with a rigid tooth-shaped surface on the outer edge, and is axially fixed to the joint on one side of the threaded coupling 22. The ratchet wheel 41 rotates unidirectionally during the installation of the splicing track, and the rotation of the ratchet wheel drives the threaded coupling 22 to rotate synchronously.

[0026] Specifically, the handle 42 is Y-shaped, and the open end is sleeved on both sides of the ratchet wheel 41. The handle can rotate 360 degrees around the central axis of the ratchet wheel.

[0027] Specifically, the pawl 43 is a metal stop piece. One end of the pawl 43 is fixedly connected to the middle of the two forks of the handle 42, and the other end meshes with the ratchet wheel 41. When the handle 42 is rotated forward, that is, when the handle 42 rotates to drive the ratchet wheel 41 and the threaded coupling 22 to rotate, and the first pull rod 21 and the second pull rod 23 approach each other, the pawl 43 engages into the teeth of the ratchet wheel 41 and drives the ratchet wheel 41 to rotate. When the handle 42 is rotated backward, the pawl 43 slides along the tooth back of the ratchet wheel 41, and the ratchet wheel 41 does not rotate with the rotation of the handle 41.

[0028] The specific working state of the single-track crane beam track splicing device provided by the present utility model is as follows:

[0029] The claw 1 is fixed to the bottom of the splicing tracks on both sides of the required splicing position through the bolt 113 and two clamping pieces. The handle 42 is rotated repeatedly to apply a rotational force. When the handle 42 is rotated backward, the pawl 43 slides along the tooth back of the ratchet wheel 41, and the ratchet wheel 41 does not rotate with the rotation of the handle 41. When the handle is rotated forward, the pawl 43 engages into the teeth of the ratchet wheel 41. The handle 42 drives the ratchet wheel 41 and the threaded coupling 22 to rotate through the pawl 43, driving the first threaded pull rod 21 and the second threaded pull rod 23 to approach each other, and then pulling the splicing tracks fixed by the first claw 11 and the second claw 12 to approach each other, realizing the installation of the splicing tracks.

[0030] Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present utility model should also belong to the protection scope of the present utility model.
