Description

Technical Field

[0001] The utility model relates to the technical field of track installation, in particular to a convenient device for installing a hoist crane track. Background Art

[0002] Hoist crane is a light and small lifting equipment with the characteristics of small size, light weight, simple operation and easy use. Hoist crane is widely used in industrial and mining enterprises, storage terminals and other places. It is especially suitable for places with relatively limited space but requiring flexible lifting operations. As a lifting tool, hoist crane can greatly improve manpower and efficiency, reduce the burden on workers, and is an indispensable mechanical equipment in many industries.

[0003] At present, for the installation of hoist crane track, a reserved track is used, a wire rope is passed through the installation point, and the track is lifted into place by a hand hoist, the hole position is actually marked, and the hand hoist is moved and drilled, and the track is returned to the position for installation; the hand hoist at the original track installation point is removed, and the installation ear plate is installed, the hole position is actually marked, the ear plate is removed and drilled, the ear plate is installed, and the track is returned to the position; in case of through-wall installation, the end ear plate needs to be welded first, and when the track has not reached the height, the hand hoist is used to diagonally pull the track through, and then return to the position. This installation method is relatively cumbersome, time-consuming and labor-intensive, and has the problem of low efficiency. Therefore, a convenient device for installing hoist crane track is needed for this situation. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] See also Figures 1 to 4The utility model provides a technical solution: a convenient device for installing a hoist crane rail, comprising two fixing hangers 1 fixed to both sides of a concrete beam by fixing bolts 2, and further comprising a fixing hole 12 provided at the bottom of the fixing hanger 1, and a rail fixing bolt 13 provided inside the fixing hole 12. After the hoist crane rail is pushed into the bearing support plate 4 by the rail fixing bolt 13, the hoist crane rail is fixed to prevent it from moving during use. One side of the fixing hanger 1 is provided with multiple bearing support plates 4 by connecting bolts 3, and one side of the bearing support plate 4 is provided with a lifting groove 5 for installing the hoist crane rail. The size and shape of the lifting groove 5 are adapted to the size and shape of the hoist crane rail. The figure takes a hoist crane rail of No. 63 I-beam as an example. In actual use, the lifting groove 5 of corresponding size and shape is selected according to the installed rail, so that the device is not limited to the hoist crane rail, and can be simultaneously applied to the installation of different types of rails on concrete beams.

[0019] Two connecting plates 6 are arranged between every two bearing support plates 4. The figure takes the hoist crane track of No. 63 I-beam as an example. The heights of the two connecting plates 6 are different, and the pin shafts 7 installed on the two connecting plates 6 are tilted to adapt to the inclined contact surface of No. 63 I-beam. The surface of the connecting plate 6 is provided with a rolling bearing 8 through the pin shaft 7. The rolling bearing 8 is used to reduce friction, and the hoist crane track can be directly pushed into the bearing support plate 4, saving time and effort, and effectively avoiding the heavy and dangerous labor of construction personnel to install the track by manually pulling the hoist. The pin shaft 7 passes through the mounting hole 10 on the surface of the connecting plate 6, and a blocking nut 11 is provided at one end. The diameter of the rolling bearing 8 is higher than the lower surface of the lifting groove 5, so that the rolling bearing 8 contacts the hoist crane track. Gaskets 9 are provided on both sides of the rolling bearing 8, so that the device has the advantages of simple structure, low manufacturing cost, simple installation and disassembly, and can be used repeatedly.

[0020] In the present invention, the working steps of the device are as follows:

[0021] First, pass the pin 7 with the rolling bearing 8 and the gasket 9 through the mounting hole on the connecting plate 6, and then fix it with the blocking nut 11. Then, use the connecting bolts 3 to install the two sets of bearing support plates 4 on one side of the fixed hanger 1 with the hanging groove 5 facing each other. Then, drill holes on both sides of the concrete beam to be installed, and install the fixed hanger 1 with the fixing bolts 2.

[0022] Then, use a car crane to lift the pre-installed track (i.e. the track with the end welded and the lifting point sealed) with two steel wire ropes of the same length. Take two points at one-third of the track beam and lock them with shackles. Tie ropes at both ends. Leave about 3 meters of rope at one end (the end that goes into the room) and the other end at a controllable length on the ground for lifting.

[0023] When the rail is hoisted to be parallel to the bearing support plate 4, the operator uses the swing rope to position it and directs the crane to pass the rail into the bearing support plate 4. The rail is pulled into each bearing support plate 4 one by one by the hand winch. When the rail is completely in contact with the bearing support plate 4 and the fixed hanger 1 on the concrete beam, the rail is fixed by passing the rail fixing bolt 13 through the fixing hole 12 at the bottom of the fixed hanger 1.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
