A travel steering system is arranged on the lower surfaces of the front and rear ends of each lower longitudinal beam, and each travel steering system is respectively connected to the hydraulic pump of the hydraulic station. It uses four travel steering systems to realize the horizontal movement, vertical movement, 360° rotation in situ, and braking of the gantry crane. The flexibility of the gantry crane is greatly improved.

[0003] However, the hydraulic drive of the travel steering system is realized by connecting the hydraulic pump with the travel steering system.

In some scenarios, it is necessary to use hoisting and transportation equipment in a relatively closed tunnel, and the working noise of the hydraulic system will seriously interfere with the working status of other personnel in the tunnel. In other words, the gantry crane it provides is not convenient to use in a tunnel environment. Utility Model Content

[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 as well as Figure 2 As shown, the present application provides a lifting and transportation equipment suitable for a tunnel environment, which includes: a frame 1 and a lifting device 2, the lifting device 2 is installed on the frame 1 and is located in a lifting space formed inside the frame 1, and the lifting device 2 is used to lift heavy objects.

[0026] Traveling wheels 3 are installed at four corners of the bottom of the frame 1 , and each of the four traveling wheels 3 is connected to a corresponding driving motor 4 , and the traveling wheels 3 are driven by the driving motor 4 to travel.

[0027] When in use, the heavy objects can be lifted by the lifting device 2, and the four driving motors 4 can be controlled to drive the driving wheels 3 at the bottom of the frame 1. Since the four driving wheels 3 are installed at the four corners of the bottom of the frame 1, the forward direction and forward speed of the lifting and transporting equipment can be adjusted by controlling the driving state of the driving wheels 3, so as to realize flexible regulation in the tunnel environment. The heavy objects are lifted to the target location.

[0028] Because the driving wheel 3 is driven by the driving motor 4, compared with the hydraulic system drive, the noise is relatively smaller, and the echo generated in the closed environment is relatively smaller, which has less interference to other workers in the tunnel.

[0029] like Figure 1 as well as Figure 2 As shown, the frame 1 includes a load-bearing member 11, and each of the four corners of the load-bearing member 11 is connected to a column 12, wherein the bottoms of two columns 12 are commonly connected to a first bottom beam 13, and the bottoms of the other two columns 12 are commonly connected to a second bottom beam 14, and the first bottom beam 13 and the second bottom beam 14 are of the same height and their ends are aligned. The load-bearing member 11 and the four columns 12 define a hoisting space, and the hoisting device 2 installed on the load-bearing member 11 is located in the hoisting space.

[0030] Each of the four corners of the load-bearing member 11 is connected with a column 12, and the four columns 12 can enclose a space for hanging heavy objects. During the hoisting process, the heavy objects hoisted are located below the hoisting device 2 and are mainly accommodated in the hoisting space. The columns 12 can be used to reduce the probability of components in the use space directly colliding with the hoisted heavy objects. The hoisted objects can be better protected.

[0031] like Figure 2 , Figure 3 as well as Figure 4 As shown, in some implementations, the load-bearing member 11 includes two first connecting beams 111 and two second connecting beams 112, the first connecting beams 111 and the second connecting beams 112 are alternately connected to form a frame structure, the columns 12 are connected to the first connecting beams 111, one side of the lifting device 2 is connected to one second connecting beam 112, and the other side of the lifting device 2 is connected to another second connecting beam 112.

[0032] That is to say, the weight of the lifting device 2 is transferred to the first connecting beam 111 through the second connecting beam 112, and then transferred to the column 12 by the first connecting beam 111. Since different second connecting beams 112 are connected to the two sides of the lifting device 2, the weight of the lifting device 2 can be distributed to the two second connecting beams 112, thereby reducing the load-bearing capacity of the single second connecting beam 112. Furthermore, since different first connecting beams 111 are connected to the two ends of the second connecting beam 112, the weight it carries can be distributed to the two first connecting beams 111. Through the above two force distribution processes, the weight of the lifting device 2 can be relatively evenly distributed to the four columns 12. The load-bearing capacity of a single column 12 is reduced, thereby extending the service life of the lifting and transportation equipment.

[0033] See also Figure 1 as well as Figure 2 As shown, in some implementations, the length direction of the second connecting beam 112 , the length direction of the first bottom beam 13 , and the length direction of the second bottom beam 14 are in the same direction, and the length direction of the first connecting beam 111 is perpendicular to the length direction of the second connecting beam 112 .

[0034] That is to say, the directions of the beams in the frame 1 are relatively regular, mainly arranged in parallel and vertically, and connected to each other to form a frame structure, which reduces the difficulty of building the frame 1.

[0035] like Figure 2 and Figure 4 As shown, in some implementations, each column 12 is connected to a corresponding reinforcing beam 15, and one end of the reinforcing beam 15 away from the column 12 is connected to the load-bearing member 11, and the reinforcing beam 15, the column 12 and the load-bearing member 11 form a triangular structure. Since the reinforcing beam 15 is arranged between the column 12 and the load-bearing member 11, the anti-deformation ability of the three-dimensional and the load-bearing member 11 can be improved by forming a triangular structure with the reinforcing beam 15, so that the frame 1 can meet the hoisting of heavier objects. In the present application, the end of the reinforcing beam 15 away from the column 12 is connected to the bottom of the first connecting beam 111.

[0036] like Figure 2 as well as Figure 3 As shown, in some implementations, the second connecting beam 112 is provided with a first mounting structure 1121 , and a center line connecting the first mounting structure 1121 of the second connecting beam 112 forms a first straight line, and the two first connecting beams 111 are symmetrical along the first straight line.

[0037] Since the two first connecting beams 111 are symmetrical along the first straight line, that is, the force application point first mounting structure 1121 is equidistant from the two first connecting beams 111 , the second connecting beam 112 can evenly transfer the weight it carries to the two first connecting beams 111 .

[0038] like Figure 1 as well as Figure 2 As shown, in some implementations, an electric control box 5 is installed on the frame 1, and the four drive motors 4 are all connected to the electric control box 5. The electric control box 5 is also wirelessly connected to a remote control device, and the remote control device is configured to remotely control the electric control box 5 to achieve remote control of the four drive motors 4.

[0039] That is to say, the user can remotely operate the crane to complete the driving work. Among them, the electric control box 5 in this application is provided with a PLC (Programmable Logic Controller) controller, and the PLC controller has the characteristics of strong versatility, convenient use, wide adaptability, high reliability, strong anti-interference ability, and simple programming. The PLC controller is connected to the four drive motors 4 through a frequency converter to realize the control of the four drive motors 4. At the same time, the PLC controller is also connected to the rocker-type remote control device through a remote control signal to meet the remote control requirements of the remote control device.

[0040] In the present application, the electric control box 5 will also collect the speed signal of the drive motor 4 , and the electric control box 5 will perform closed-loop control of the drive motor 4 according to the speed signal of the drive motor 4 .

[0041] like Figure 1 as well as Figure 2As shown, in some implementations, the output shaft of the driving motor 4 is connected to the corresponding running wheel 3 through a transmission chain 6, and each transmission chain 6 outer cover is provided with a corresponding first cover body 7 (the first cover body 7 of the transmission chain 6 corresponding to the running wheel 3 on the front side of the first bottom beam 13 is hidden and not shown), and the first cover body 7 is installed on the frame 1. The driving motor 4 drives the running wheel 3 through the transmission of the transmission chain 6. Compared with gear transmission or direct connection of the motor, the chain connection installation using the transmission chain 6 is more flexible. In addition, since the outer cover of the transmission chain 6 is provided with a first cover body 7 installed on the frame 1, it can prevent the transmission chain 6 from contacting too many foreign objects and reducing the transmission efficiency.

[0042] In some implementations, the lifting device 2 is detachably mounted on the frame 1 .

[0043] Specifically, in the present application, the lifting device 2 is detachably mounted in the load-bearing member 11 using a bolt structure. Since the lifting device 2 is detachably mounted on the load-bearing member 11, when it is necessary to match the lifting device 2 of different specifications, the lifting device 2 on the load-bearing member 11 can be replaced to achieve the lifting of different types of workpieces.

[0044] like Figure 1 as well as Figure 2 As shown, in some implementations, the outer side of the frame body 1 is also rotatably connected with a guide anti-collision rolling body 8, and the rotation axis of the guide anti-collision rolling body 8 is arranged vertically.

[0045] By setting a guiding anti-collision rotating body on the outside of the frame 1, when the lifting and transportation equipment collides with the tunnel wall or related equipment, the wall and the equipment will first collide with the guiding anti-collision rotating body. With the help of the rotation of the guiding anti-collision rotating body, part of the energy of the collision can be eliminated, thereby reducing the damage to the frame 1 caused by the collision.

[0046] like Figure 1 as well as Figure 2 As shown, in some implementations, a second cover 9 is correspondingly provided outside each running wheel 3, the second cover 9 is mounted on the frame 1, and the bottom of the running wheel 3 extends out of the second cover 9. By installing the second cover 9 provided outside the running wheel 3 on the frame 1, damage to the running wheel 3 by foreign objects can be reduced, and the service life of the running wheel 3 can be extended.

[0047] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
