Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting and transportation equipment, and particularly relates to a monorail crane suitable for narrow spaces. Background Art

[0002] Monorail crane, full name is flexible monorail suspension crane, is a kind of lifting and transportation equipment that can run on a single track. It is usually used for linear transportation of materials and is suitable for space-constrained environments, such as mine tunnels, warehouses, workshop interiors and construction sites. Monorail cranes are widely used in many fields due to their strong maneuverability, fast running speed, large load capacity and safety and reliability. Monorail cranes suitable for narrow spaces are specially designed to operate in environments with limited space. They can effectively use vertical space for material handling, reduce ground occupancy and improve space utilization.

[0003] The existing monorail crane in narrow space realizes the lifting of materials through the winch on the crossbeam. When the height of the material to be lifted is too high and exceeds the lifting height of the winch, the height of the lifting frame cannot be adjusted to increase the upper limit of the lifting height, making it unable to adapt to the height requirements of different lifting points, limiting its application at working points at different heights and greatly reducing its flexibility. Utility Model Content

[0004] In view of this, the utility model aims to address the deficiencies in the prior art and provides a monorail crane suitable for narrow spaces. The frame height can be automatically and flexibly adjusted to increase the upper limit of the hoisting of the winch. The appropriate hoisting height of the material can be quickly adjusted according to the specific needs of the work site, adapting to a wider variety of work tasks and environments, greatly improving its flexibility.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a monorail crane suitable for narrow spaces, comprising two slide frames corresponding to left and right positions, the slide frames are slidably arranged inside the slide frames, a crossbeam is arranged between the upper ends of the two slide frames, a frame plate is slidably arranged on the outer side of the crossbeam, four walking wheels are rotatably connected inside the frame plate, the four walking wheels are installed in cooperation with a crossbeam, a winch is arranged at the lower end of the frame plate, an electric drive unit 1 for driving the walking wheels to rotate is arranged on the front and rear sides of the frame plate, a height adjustment mechanism is arranged inside the two slide frames, the electric drive unit 1 includes a motor 1 respectively arranged on the front and rear sides of the frame plate, the output shafts of the two motors 1 are respectively connected to the outer ends of the two walking wheels on the left side through a coupling, and the height adjustment mechanism includes The cam plates are respectively arranged inside the two slide frames, and two rotating seats corresponding to the front and rear positions are slidably arranged inside the two slide frames, and the four rotating seats are rotatably connected with connecting rods inside. The lower end of the sliding frame is provided with two rotating frames corresponding to the left and right positions, and the two front and rear adjacent connecting frames are respectively rotatably connected to the adjacent rotating frames. Two screw rods are rotatably arranged inside the two slide plates, and the four rotating seats are respectively threadedly connected to the adjacent screw rods. An electric drive unit 2 for driving the screw rods to rotate is arranged inside the two slide plates, and the thread directions of the two screw rods located inside the same slide plate are opposite. The electric drive unit 2 includes two motors respectively arranged inside the two slide plates, and the output shafts on the front and rear sides of the motor 2 are respectively connected to the inner ends of the adjacent screw rods through couplings.

[0006] As a further improvement of the utility model, a placement frame is provided at the upper end of the crossbeam, a control panel is placed inside the placement frame, and the motor 1, the motor 2 and the winch are all electrically connected to the control panel.

[0007] As a further improvement of the utility model, two mounting plates are welded and fixed to the lower end of the slide frame.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] Firstly, the lifting hook of the winch can be raised and lowered by the control panel to realize the rapid lifting of the goods. The motor can also be turned on by the control panel. The output shaft drives the two walking wheels on the left to rotate to realize the left and right movement of the winch, so that materials in different positions can be lifted quickly.

[0010] Secondly, the control panel is used to control the operation of motor 2, and the output shaft drives the screw rods on both sides to rotate. Since the screw rods on both sides have opposite threads, the rotating seats on both sides approach each other, and the connecting rods inside them rotate and contract, thereby driving the winch on the sliding frame to move upward under the restriction of the slide frame, thereby quickly adjusting the lifting height. The frame height can be automatically and flexibly adjusted to increase the upper limit of the lifting of the winch. It can quickly adjust the appropriate lifting height of the material according to the specific needs of the job site, adapt to more types of work tasks and environments, and greatly improve its flexibility.

DETAILED DESCRIPTION

[0019] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0020] like Figure 1 ,2 As shown in Figures 3 and 4, a monorail crane suitable for narrow spaces comprises two slide frames 101 corresponding to left and right positions, the slide frames 101 are both slidably provided with slide frames 102, a crossbeam 103 is provided between the upper ends of the two slide frames 102, a frame plate 107 is slidably provided on the outer side of the crossbeam 103, four running wheels 108 are rotatably connected inside the frame plate 107, the four running wheels 108 are installed in cooperation with a crossbeam 103, a winch 109 is provided at the lower end of the frame plate 107, an electric drive unit 1 for driving the running wheels 108 to rotate is provided on the front and rear sides of the frame plate 107, a height adjustment mechanism is provided inside the two slide frames 101, the electric drive unit 1 comprises motors 110 respectively provided on the front and rear sides of the frame plate 107, and the output shafts of the two motors 110 are respectively connected to the outer ends of the two running wheels 108 on the left side through couplings.

[0021] like Figure 1 , 3 As shown in , 4, the height adjustment mechanism includes a slide plate 201 respectively arranged inside the two slide frames 101, two rotating seats 203 corresponding to the front and rear positions are slidably arranged inside the two slide plates 201, and the four rotating seats 203 are rotatably connected to the connecting rod 204 inside. The lower end of the sliding frame 102 is provided with two rotating frames 205 corresponding to the left and right positions, and the two front and rear adjacent connecting frames are respectively rotatably connected to the adjacent rotating frames 205 inside. Two screw rods 202 are rotatably arranged inside the two slide plates 201, and the four rotating seats 203 are respectively threadedly connected to the adjacent screw rods 202. The two slide plates 201 are each provided with an electric drive unit 2 for driving the screw rods 202 to rotate. The thread directions of the two screw rods 202 located in the same slide plate 201 are opposite. The electric drive unit 2 includes a motor 206 respectively arranged inside the two slide plates 201, and the output shafts on the front and rear sides of the motor 206 are respectively connected to the inner ends of the adjacent screw rods 202 through couplings.
