Description

Technical Field

[0001] The utility model relates to the field of rigid track structures, in particular to a rigid hanging point structure for a track. Background Art

[0002] The lifting point structure of the track is generally divided into two types: rigid lifting point and flexible lifting point. Among them, the rigid lifting point structure is fixed, so it has better stability and higher safety during the lifting process. Therefore, it has been widely used in construction, machinery, and petrochemical industry.

[0003] The rigid lifting point structure is generally composed of main beams, rails, hoist trolleys, rail hanging parts and other components. Among them, the top of the lifting point is generally composed of two types of beam structures: single beam and double beam. When the object exceeds the bearing capacity of the single beam, the single beam needs to be replaced. However, the existing single beam and double beam are made separately, and the single beam needs to be completely disassembled before the double beam can be replaced. However, the installation and disassembly of the rigid lifting point structure is relatively difficult, which requires more time and effort, increases the work cost, and also leads to poor adaptability when facing the lifting of different objects. Utility Model Content

[0004] The utility model aims to provide a rigid suspension point structure for rails, which effectively solves the problems that the traditional single-beam rigid suspension point structure is difficult to install and disassemble when it is converted into a double-beam suspension point structure, cannot achieve rapid replacement between single and double beams, and has poor adaptability.

[0005] The technical solution of the utility model is as follows:

[0006] A rigid suspension point structure for a track, comprising a left track and a right track parallel thereto, a left beam body and a right beam body respectively arranged above the left and right tracks, track grooves arranged inside the left and right tracks, a hoist trolley arranged inside the track grooves, a mounting plate arranged at the bottom of the hoist trolley, an electric power system at the bottom end of the mounting plate, a suspension structure connected to the electric power system, a threaded positioning plate arranged between the top ends of the left track and the right track, positioning grooves corresponding to the positions of the two side plates of the left beam body and the right beam body, and a positioning beam arranged in the positioning grooves;

[0007] A baffle is provided at the tail end of the positioning beam, a through slot is provided inside the positioning beam, two sections of slide slots are provided on the top plate of the positioning beam near the front and rear ends, a T-shaped slide bar is provided in the through slot, the transverse section of the slide bar is elastic and retractable, and telescopic blocks are provided at both ends of the transverse section, and the vertical section of the slide bar extends upward into the slide slot;

[0008] The left and right side plates of the positioning beam are provided with positioning holes corresponding to the spaced distribution positions, the telescopic blocks extend from the positioning holes, and the telescopic blocks are provided with fasteners for locking with the left track and the right track.

[0009] Furthermore, the power system includes electrical power and gas power for driving the hoisting structure to work, so that the hoisting structure can work normally.

[0010] Furthermore, the cross section of the baffle is circular, and its outer dimensions are larger than those of the through slot, so that when the positioning beam is inserted into the last section, the tail end can fit the left beam body.

[0011] Furthermore, the positioning groove is a tapered structure that is small at the top and large at the bottom, and the shape of the positioning beam matches the shape of the positioning groove, so that insertion can be achieved.

[0012] Furthermore, the positions of the positioning grooves on the left beam body and the right beam body correspond one to one, and the number of the positioning grooves on the left and right beam bodies is not less than two, thereby ensuring the stability of the connection between the left beam body and the right beam body.

[0013] Furthermore, a paddle is provided at the top of the vertical section of the slide rod, and the top wall height of the paddle is lower than the top wall of the positioning beam, so that the positioning beam can be inserted into the positioning groove without obstruction.

[0014] Furthermore, the total length of the two telescopic blocks is smaller than the width of the through slot, so that when the telescopic blocks are fully extended into the through slot, the positioning beam can slide.

[0015] The advantages of the utility model are:

[0016] 1. The utility model provides left and right tracks and left and right beam structures, so that when a single beam exceeds the load, there is no need to disassemble the single beam as a whole and then replace the double beam. Instead, a new single beam is directly added to the single beam to realize the double beam, which reduces the installation and disassembly process, saves costs, and improves the efficiency during the lifting process.

[0017] 2. The utility model sets a positioning beam, which is inserted into a pre-set positioning groove. The sliding rod is moved to insert the telescopic block into the positioning hole, and the fastener is used to lock the two single beams, thereby achieving a fixed connection between the two single beams. The structure is simple and flexible, and the plug-in connection method is faster and more convenient than the traditional screw locking method.

[0018] 3. The utility model can adjust the left and right beams of different widths by arranging the locating holes distributed at intervals on the locating beam, thereby improving flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The cross section of the baffle 13 is circular, and its outer dimensions are larger than those of the through slot 14 , so that when the positioning beam 12 is inserted into the rear end, the rear end can fit the left beam body 3 .

[0030] The positioning groove 11 is a tapered structure that is small at the top and large at the bottom. The shape of the positioning beam 12 matches the shape of the positioning groove 11, so that insertion can be achieved.

[0031] The positions of the positioning grooves 11 on the left beam body 3 and the right beam body 4 correspond one to one, and the number of the positioning grooves 11 on the left and right beam bodies is not less than two, thereby ensuring the stability of the connection between the left beam body 3 and the right beam body 4.

[0032] A paddle is provided at the top of the vertical section of the slide bar 16 , and the top wall height of the paddle is lower than the top wall of the positioning beam 12 , so that the positioning beam 12 can be inserted into the positioning groove 11 without obstruction.

[0034] Detailed usage and effects of the above embodiments:

[0035] The beam is connected to the C-shaped steel through the track hanging parts. The C-shaped steel is fixed on the ground, which is not shown in the figure, to realize the structure of the entire rigid track. When a rigid lifting point is required, the lifting structure 9 first lifts the object, and then drives the hoist trolley 6 on the beam body through the power system 8 to move. For ordinary objects, the lifting is adopted. Figure 4 In the single-beam lifting method, if the hoisted object is larger than the single-beam lifting capacity.

[0036] Initially, the left rail 1 and the right rail 2 are simply locked by the positioning plate 10. The left beam 3 and the right beam 4 are provided with positioning grooves 11. The positioning beam 12 is taken out and inserted into the positioning groove 11 so that the baffle 13 at the tail end of the positioning beam 12 is against the left beam 3. At this time, the slide bar 16 is toggled to move the slide bar 16 in the slide groove 15. In the initial state, the telescopic block 17 is hidden in the through groove 14. The transverse section of the slide bar 16 is a telescopic elastic rod. When it moves to a suitable position, the telescopic blocks 17 connected at both ends pop out from the positioning holes 18. Through the spacing positioning holes 18, the distance between the two telescopic blocks 17 is adjusted so that the telescopic blocks 17 fit on the side plates of the left beam 3 and the right beam 4. At this time, the fastener 19 is taken out, and the positioning beam 12 and the left and right beams are fixed by the fastener 19, so as to realize the rapid replacement of single beam to double beam.
