Description

Technical Field

[0001] The utility model relates to the technical field of cable cranes, in particular to a connection structure for butting a main cable and an anchor cable of a cable crane. Background Art

[0002] Cable crane, also called cable pulley, is a crane with a lifting trolley with a lifting device running along an overhead load cable. It is often used in situations where other lifting methods are inconvenient or uneconomical, and in situations where the lifting weight is not large but the span and height are large, such as bridge construction, TV tower top equipment lifting, etc.

[0003] At the connection point where the main cable and anchor cable of an existing cable crane are connected, the load-bearing main cable is generally directly wound around the pulley. Due to the lack of an integrated structure that can limit the load-bearing main cable, the load-bearing main cable is easily detached from the pulley, which affects the normal use of the cable crane. For this reason, we provide a connection structure for connecting the main cable and anchor cable of a cable crane. Utility Model Content

[0004] In order to solve the problem in the above background technology that it is difficult to limit the load-bearing main cable on the pulley, so that the load-bearing main cable is easily separated from the pulley, the utility model provides a connection structure for connecting the main cable of a cable crane with an anchor cable.

[0005] The utility model adopts the following technical solution: a connection structure for connecting the main cable and the anchor cable of a cable crane, comprising:

[0006] A special pulley, on which anchor cables are symmetrically and equidistantly fixedly connected through anchor pieces, a load-bearing main cable is wound around the outside of the special pulley, and a rope clamp is equidistantly and fixedly connected between the working section and the tail section of the load-bearing main cable;

[0007] A main rope clamping assembly, which includes two groups of connecting brackets symmetrically fixedly connected to a special pulley through connecting columns, both groups of connecting brackets are provided with strip slides, the inside of the strip slides is slidably connected with a slide plate, a small pulley is rotatably connected between the two groups of slide plates and the small pulley is in contact with the load-bearing main rope, the upper and lower parts of both sides of the special pulley are symmetrically fixedly connected with sliding rods, the outside of the sliding rods is slidably connected with sliders, the upper two groups of sliders and the lower two groups of sliders are fixedly connected with the same connecting frame, a pressure roller is rotatably connected to the connecting frame, the outside of the slide plate is fixedly connected with a connecting frame, and a connecting rod is hinged between the connecting frame and the connecting frame.

[0008] As a further improvement of the above scheme, the special pulley includes two groups of wall panels, a pressure plate is horizontally fixedly connected between the two groups of wall panels, a stiffening plate is vertically symmetrically fixedly connected between the two groups of wall panels and the stiffening plate and the pressure plate are fixedly connected, and a large pulley is rotatably connected between the two groups of wall panels through an axis.

[0009] As a further improvement of the above solution, a rope groove is provided on the surface of the large pulley.

[0010] As a further improvement of the above solution, the number of the rope clamps is 12 groups, and the spacing between adjacent rope clamps is equal to 6 to 7 times the rope diameter.

[0011] As a further improvement of the above solution, the distance between the rope clamp at the end and the tail section of the load-bearing main rope is greater than 6 times the rope diameter.

[0012] As a further improvement of the above solution, the angle between the working section and the tail section of the load-bearing main cable is 29 degrees.

[0013] As a further improvement of the above solution, a spring is sleeved outside the sliding rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model uses the load-bearing main rope to pull the large pulley. Due to the effect of traction, the load-bearing main rope will squeeze the small pulley. After being squeezed, the small pulley will slide toward the large pulley. At the same time, the movement of the slide plate will drive the connecting frame to move. The connection frame and the hinged effect between the connecting frame and the connecting rod can be used to push the upper and lower sliding blocks to slide back to each other outside the sliding rod, so that the upper and lower pressure rollers can be driven to approach the large pulley at the same time to press down the load-bearing main rope inside the rope groove to limit the position, thereby effectively avoiding the problem that the load-bearing main rope is easily separated from the pulley. The utility model has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please combine Figure 1-6 A connection structure for connecting a main cable and an anchor cable of a cable crane according to this embodiment includes:

[0026] A special pulley 1, on which an anchor cable 2 is symmetrically and equidistantly fixedly connected through an anchor piece, a load-bearing main cable 3 is wound around the outside of the special pulley 1, the rope diameter of the load-bearing main cable 3 is 60 mm, a rope clamp 4 is equidistantly and fixedly connected between the working section and the tail section of the load-bearing main cable 3, the angle between the working section and the tail section of the load-bearing main cable 3 is 29 degrees, the number of rope clamps 4 is 12 groups, the spacing between adjacent rope clamps 4 is equal to 6 to 7 times the rope diameter, the spacing between the end rope clamp 4 and the tail section of the load-bearing main cable 3 is greater than 6 times the rope diameter, and the sum of the horizontal distance between the head end rope clamp 4 and the outer diameter of the large pulley 1004 and the diameter of the large pulley 1004 is greater than 2.5 times the diameter of the large pulley 1004;

[0027] The special pulley 1 includes two groups of wall panels 1001, the length of the wall panels 1001 is 360 mm, the thickness is 20 mm, and the height is 1200 mm. A pressure plate 1002 is horizontally fixedly connected between the two groups of wall panels 1001. The length of the pressure plate 1002 is 360 mm, the width is 145 mm, and the thickness is 30 mm. A stiffening plate 1003 is vertically symmetrically fixedly connected between the two groups of wall panels 1001, and the stiffening plate 1003 is fixedly connected to the pressure plate 1002. The length of the stiffening plate 1003 is 145 mm and the height is 200 mm. A large pulley 1004 is connected between the two groups of wall panels 1001 through an axial rotation, and a rope groove is provided on the surface of the large pulley 1004 to prevent the load-bearing main cable 3 from slipping off the large pulley 1004.

[0028] The main rope clamping assembly includes two groups of connecting brackets 101 symmetrically fixedly connected to the special pulley 1 through connecting columns, and the two groups of connecting brackets 101 are provided with strip slides, and the inside of the strip slides is slidably connected with a slide plate 102, and a small pulley 103 is rotatably connected between the two groups of slide plates 102, and the small pulley 103 is in contact with the load-bearing main rope 3, and the upper and lower parts of both sides of the special pulley 1 are symmetrically fixedly connected with slide rods 104, and the outside of the slide rods 104 is slidably connected with sliders 105, and the same connecting frame 106 is fixedly connected between the upper two groups of sliders 105 and the lower two groups of sliders 105, and a pressure roller 107 is rotatably connected to the connecting frame 106, and a connecting frame 108 is fixedly connected to the outside of the slide plate 102, and a connecting rod 109 is hinged between the connecting frame 108 and the connecting frame 106.

[0029] The implementation principle of a connection structure for connecting the main cable and the anchor cable of a cable crane in the embodiment of the present application is as follows: first, the load-bearing main cable 3 is sleeved on the outside of the small pulley 103 and the large pulley 1004, and then the working section and the tail section of the load-bearing main cable 3 are fixed by the rope clamp 4, and finally the special pulley 1 is fixed to the ground by the anchor and the anchor cable 2. When the load-bearing main cable 3 is pulling the large pulley 1004, the load-bearing main cable 3 will squeeze the small pulley 103 due to the traction force, and the sliding plate 102 is used to slide with the strip slide groove, so that the small slide After being squeezed, the wheel 103 will slide toward the large pulley 1004. At the same time, the movement of the slide plate 102 will drive the connecting frame 108 to move together. By utilizing the hinged effect between the connecting frame 108 and the connecting frame 106 and the connecting rod 109, the upper and lower sliders 105 can be pushed to slide back to back outside the slide rod 104, thereby driving the upper and lower pressure rollers 107 to approach the large pulley 1004 at the same time to press down the load-bearing main rope 3 inside the rope groove to limit the position, thereby effectively avoiding the problem of the load-bearing main rope 3 being easily detached from the pulley. Example

[0030] The present embodiment is further improved on the basis of the embodiment 1 in that a spring 110 is sleeved outside the sliding rod 104, and after the compression of the load-bearing main rope 3 is lost, the elastic effect of the spring 110 is utilized to enable the small pulley 103 to automatically reset.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
