Description

Technical Field

[0001] The present application relates to the technical field of beam lifting machine construction, and in particular to a rail clamp tooling for a beam lifting machine. Background Art

[0002] The beam lifting machine is specially designed for bridge construction. The beam lifting machine is mainly composed of assembled main beams, outriggers, overhead cranes, etc. The components are connected by pins and high-strength bolts, which are easy to disassemble and transport. Compared with ordinary gantry cranes, it is convenient and fast to install, economical and practical. It is suitable for road and bridge construction units that often move.

[0003] During the use of the beam lifting machine, the beam lifting machine slides on the track. When the beam lifting machine slides to the specified position, it starts to work. In order to prevent the beam lifting machine from sliding during use, the beam lifting machine is usually fixed on the track. The current common fixing method is to set a locking rod on the bottom thread of the beam lifting machine, and a pad that is pressed against the ground is set at the bottom of the locking rod. When locking, the locking rod is rotated to make the pad press against the ground, so that the beam lifting machine is fixed.

[0004] Although this method can fix the beam lifting machine on the ground, it has requirements on the softness and flatness of the ground. When the pad is pressed against the ground, it is easy to cause the connection between the rail wheel and the track to be loose. When the center of gravity of the beam lifting machine shifts, it is easy to cause the beam lifting machine to derail. Therefore, a locking tool is needed that is easy to lock the beam lifting machine and reduce the probability of derailment of the beam lifting machine. Utility Model Content

[0005] In order to facilitate locking of the beam lifting machine and reduce the probability of the beam lifting machine derailing, the present application provides a rail clamp tooling for the beam lifting machine.

[0006] The rail clamp tooling of the beam lifting machine provided in this application adopts the following technical solution:

[0007] The rail clamp tooling of the beam lifting machine comprises a rail clamp block slidably arranged on the beam lifting machine, the rail clamp blocks are symmetrically arranged in two groups and used to clamp and fix the two ends of the rail, and the two groups of rail clamp blocks are provided with locking components for locking the rail clamp blocks on the rail, and the locking components include:

[0008] A double-headed screw rod, which is slidably disposed on the rail clamping block and passes through another set of rail clamping blocks;

[0009] Two groups of locking nuts are threadedly connected to the two ends of the double-headed screw and press the two groups of rail clamping blocks in a direction of approaching each other.

[0010] By adopting the above technical scheme, when the beam lifting machine moves to the specified position, the double-headed screws are installed on the two sets of rail clamping blocks, and the two sets of locking nuts are threadedly connected to the two ends of the double-headed screws. The locking nuts are rotated to tighten the two opposite ends of the two sets of rail clamping blocks, which is convenient for locking the beam lifting machine, thereby facilitating the locking of the beam lifting machine and reducing the probability of derailment of the beam lifting machine.

[0011] Furthermore, clamping blocks are arranged on opposite sides of the two groups of rail clamping blocks. The clamping blocks are arranged on one end of the rail clamping blocks close to the rail and are used to press against the end surface of the rail for fixing.

[0012] By adopting the above technical solution, when the two sets of track clamping blocks approach each other, the protruding position of the track is clamped onto the spring pad in the fixing groove, and the side wall of the clamping block is pressed against the side wall of the track, thereby clamping and fixing the beam lifting machine, enhancing the force of the track on the beam lifting machine and reducing the probability of the beam lifting machine derailing.

[0013] Furthermore, a fixing groove is provided on one end of the clamping block close to the track, and two groups of the fixing grooves are symmetrically arranged and used to abut and fix the two opposite end surfaces of the track, and the bottom of the fixing groove is used to abut and fix the track.

[0014] By adopting the above technical solution, when the two groups of track clamping blocks are close to each other, the lower bottom wall of the fixed groove is pressed against the lower surface of the protruding position of the track, thereby enhancing the connection strength between the track clamping block and the track. When the center of gravity of the beam lifting machine shifts, the force of the track on the beam lifting machine is enhanced, thereby reducing the probability of the beam lifting machine derailing.

[0015] Furthermore, a support rod is provided on the locking nut for facilitating the rotation of the locking nut, and the axis of the support rod is perpendicular to the axis of the locking nut.

[0016] By adopting the above technical solution, when in use, the staff holds the support rod and uses the support rod as a support force arm to facilitate the rotation of the locking nut, thereby improving the convenience of loosening or locking the locking nut.

[0017] Furthermore, the support rods are provided in multiple groups, and the multiple groups of support rods are arranged in a circular array on the locking nut.

[0018] By adopting the above technical solution, a single set of support rods can rotate 360 ​​degrees with the locking nut. At some angles, it is inconvenient for the staff to hold the support rods. By setting up multiple sets of support rods, the staff only needs to rotate the locking nut 360 degrees within a certain angle, which improves the convenience of loosening or locking the locking nut.

[0019] Furthermore, the support rod is provided with anti-skid patterns, and the anti-skid patterns facilitate the staff to drive the support rod to rotate.

[0020] By adopting the above technical solution, anti-slip grooves are provided on the outer side wall of the support rod, so that the staff can drive the locking nut to rotate through the support rod.

[0021] Furthermore, the support rod is hollow inside and has an opening communicating with the inside at one end away from the locking nut. An extension rod can be inserted into the support rod, and the extension rod is used to increase the support force arm of the support rod.

[0022] By adopting the above technical solution, when the locking nut and the double-headed screw are locked tightly, the force required to rotate the locking nut is large, and the force arm of the support rod is short, which makes it inconvenient to rotate the locking nut. The extension rod is inserted into the support rod to extend the support force arm of the support rod, which makes it easier to rotate the locking nut.

[0023] Furthermore, a rubber plug is provided on one end of the support rod away from the locking nut. The rubber plug is clamped on the support rod and is used to seal the opening of the support rod.

[0024] By adopting the above technical solution, the rubber plug is snap-fitted and installed at the opening of the support rod. The rubber plug is used to close the opening of the support rod to prevent debris from entering the interior of the support rod. When the extension rod needs to be installed, the rubber plug is taken out to facilitate the installation of the extension rod.

[0025] Furthermore, a spring washer is provided on the side wall of the fixing groove, and the spring washer is used to enhance the tightening effect between the clamping block and the track.

[0026] By adopting the above technical solution, the spring washer is used to enhance the clamping effect between the clamping block and the track, and at the same time, the contact between the spring washer and the track reduces the probability of track damage.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] After the beam lifting machine moves to the specified position, the double-headed screws are installed on the two sets of rail clamping blocks, and the two sets of locking nuts are threadedly connected to the two ends of the double-headed screws. The locking nuts are conveniently rotated through multiple sets of support rods to tighten the two opposite ends of the two sets of rail clamping blocks, and finally the clamping blocks are pressed against the side walls of the track to facilitate locking the beam lifting machine; at the same time, the lower bottom wall of the fixing groove is pressed against the lower surface of the protruding position of the track through spring pads, which enhances the connection strength between the rail clamping block and the track, so that when the center of gravity of the beam lifting machine shifts, the force of the track on the beam lifting machine is enhanced, reducing the probability of the beam lifting machine derailing, thereby facilitating locking of the beam lifting machine and reducing the probability of the beam lifting machine derailing.
