Abstract
Description
Technical Field
[0001] This utility model relates to the field of double-beam tire crane technology, and specifically to a double-beam tire crane. Background Technology
[0002] Double-girder tire cranes are tire-mounted cranes with a double main girder structure. They combine the mobility of tire cranes with the load-bearing stability of double-girder bridge cranes. The double main girder structure significantly improves torsional resistance, and the maximum lifting capacity can reach hundreds of tons, far exceeding the 20-ton limit of single-girder cranes. They have the advantages of fast lifting speed and high working level, and can adapt to frequent start-stop working conditions. The loading and unloading efficiency is more than 30% higher than that of single-girder cranes, making them especially suitable for scenarios such as subway tunnels and port loading and unloading.
[0003] The existing double-girder tire cranes have relatively fixed main beams. When encountering narrow places that need to be passed, the spacing between the main beams cannot be adjusted. At the same time, the spacing between the lifting mechanisms cannot be adjusted during lifting. Therefore, there is an urgent need for a double-girder tire crane to overcome the above defects. Utility Model Content
[0004] The purpose of this utility model is to provide a double-beam tire crane with the advantage of convenient adjustment, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-beam tire crane, comprising support rods, a traveling and moving mechanism, a winding and lifting mechanism, a spacing adjustment assembly, a support positioning assembly, a drive wheel, and fixed rods. The spacing adjustment assembly is disposed on one side of the support rods that are relatively close to each other, the fixed rods are disposed on both sides of the spacing adjustment assembly, the support positioning assembly is disposed at the bottom of the bottom support rod, the drive wheel is fixedly installed at the bottom of the fixed rod, the traveling and moving mechanism is fixedly installed at the top of the fixed rods that are relatively close to each other, and the winding and lifting mechanism is fixedly installed at the bottom of the traveling and moving mechanism. The total number of support rods is four. The spacing adjustment assembly includes a mounting rod, a first slider, a first threaded rod, a servo motor, a first sliding groove, and a first connecting rod. The support positioning assembly includes a U-shaped seat, a support rubber plate, a universal wheel, a limit sliding rod, a positioning groove, a cylinder, a second connecting rod, a second sliding groove, and a second slider.
[0006] Furthermore, an installation rod is fixedly installed on the side of the support rod that is relatively close to it. The installation rod has a first groove inside, and a first slider is slidably connected to both sides inside the first groove. The first slider is connected to a first threaded rod through a threaded connection.
[0007] Furthermore, the servo motor is fixedly installed on the left side of the mounting rod, and the output shaft of the servo motor passes through the inner cavity of the first slide groove and is fixedly connected to the left side of the first threaded rod. A first connecting rod is fixedly installed on the side of the first slider that is relatively close to it, and the side of the first connecting rod that is relatively far away from it is fixedly connected to the side of the fixed rod that is relatively close to it.
[0008] Furthermore, the U-shaped seat is fixedly installed at the bottom of the bottom support rod, the cylinder is fixedly installed at the center of the bottom of the bottom support rod, and the positioning grooves are all opened on both sides inside the U-shaped seat.
[0009] Furthermore, a supporting rubber plate is provided at the bottom of the U-shaped seat, and the bottom of the cylinder extends through to the bottom of the U-shaped seat and is fixedly connected to the top of the supporting rubber plate. A limit slide rod is slidably connected inside the positioning groove.
[0010] Furthermore, the bottom of the limiting slide rod is fixedly connected to the top of the supporting rubber plate, the universal wheels are all fixedly installed on both sides of the bottom of the U-shaped seat, and a second connecting rod is provided on the outer side of the supporting rod.
[0011] Furthermore, a second groove is provided inside the second connecting rod, and a second slider is slidably connected inside the second groove. The side of the second slider that is relatively close to the outside of the support rod is fixedly connected, and the side of the second connecting rod that is relatively far away from the outside of the fixed rod is fixedly connected.
[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:
[0013] This invention supports the bottom of the support rods by setting a support positioning component, adjusts the spacing of the fixed rods by setting a spacing adjustment component, adjusts the spacing of the winding and hoisting mechanism, translates the position of the winding and hoisting mechanism by setting a traveling moving mechanism, hoists the heavy object by setting the winding and hoisting mechanism, and moves the entire device by setting a drive wheel. When adjusting the spacing of the fixed rods, firstly, the cylinder is opened, which drives the support rubber plate to move downward, so that the drive wheel is lifted off the ground. Then, the servo motor is opened, which drives the first threaded rod to rotate, so that the first slider drives the first connecting rod to move outward, and simultaneously drives the fixed rod to move to both sides. After moving to the designated position, the cylinder drives the support rubber plate to move upward, so that the drive wheel contacts the ground, thereby adjusting the spacing of the fixed rods. It has the advantage of convenient adjustment and solves the problem of existing double-girder tire cranes where the main beam is relatively fixed, and when encountering narrow places, it is impossible to adjust the spacing of the crane itself, and it is also impossible to adjust the spacing of the hoisting mechanism during hoisting.

After moving to the designated position, the cylinder 56 drives the supporting rubber plate 52 to move upward, so that the drive wheel 6 contacts the ground, thereby adjusting the spacing of the fixed rods 7, which has the advantage of convenient adjustment.
