Description

Technical Field

[0001] The utility model relates to the technical field of sleeper hoisting, in particular to a hoisting device for sleepers. Background Art

[0002] Sleepers are the basic material used for laying railway lines and are important materials indispensable for railway superstructures. There are also bridge sleepers, shuttle sleepers and transition sleepers with elastic pads. In terms of loading and unloading, there are railway transportation and road transportation. A sleeper needs to be lifted and transported many times from the factory to the time it is laid on the line, so a lifting device for the sleeper is needed.

[0003] However, the existing sleeper hoisting device has some defects or shortcomings:

[0004] The existing sleeper lifting device generally uses two steel wire ropes respectively sleeved on the two ends of multiple sleepers, and then the steel wire ropes are hung by a crane for lifting. The steel wire ropes are in direct contact with the sleepers, which can easily cause the steel wire ropes and the sleepers to wear and damage, and the limiting effect of the sleepers is poor. During the lifting process, multiple sleepers are easily unstable due to lateral tension during lifting, causing the sleepers to overturn, and multiple sleepers are easily damaged by collision with each other. Alternatively, angle steel and steel wire ropes are generally used to lift multiple sleepers. However, during the lifting process, the steel wire ropes will be in an inclined state, and the contact point between the steel wire ropes and the angle steels will be subjected to uneven force, which will have a greater impact on the wear of the steel wire ropes, easily affecting the service life of the steel wire ropes, requiring frequent replacement, and easily causing safety hazards during lifting.

[0039] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0040] See also Figure 1 , Figure 1 Shows a three-dimensional diagram of the utility model; please refer to Figure 2 , Figure 2 A partial exploded view of the present invention is shown; see Figure 3 , Figure 3 Shows a partial stereoscopic view of the utility model Figure 1 ; see Figure 4 , Figure 4 Shows a partial stereoscopic view of the utility model Figure 2 ; see Figure 5 , Figure 5 The utility model is shown Figure 3 See the enlarged view of point A in Figure 6 , Figure 6 The utility model is shown Figure 4 The enlarged view of point B; Figure 1-6As shown, a hoisting device for a sleeper comprises: a steel pipe frame 1 for connecting with an external crane, two bearing frames 2 symmetrically arranged below the steel pipe frame 1 and used to bear a plurality of sleeper members 31, a plurality of steel cables 3 respectively connected to both ends of the two bearing frames 2, two positioning components 4 respectively installed on the two bearing frames 2, two stoppers 5 arranged at both ends of the two bearing frames 2, and a plurality of protection components 6 respectively arranged at both ends of the plurality of steel cables 3;

[0041] The ends of the steel cables 3 are bent into annular rings 30 by fixing parts at both ends of the steel cables 3. The annular rings 30 at the upper ends of the steel cables 3 are respectively sleeved at the four corners of the steel pipe frame 1.

[0042] The positioning assembly 4 is suitable for limiting the position of a plurality of the sleeper members 31 placed on one end of one of the supporting frames 2;

[0043] The plurality of protection components 6 are adapted to isolate the plurality of steel cables 3 from direct contact with the steel pipe rack 1 or the carrier rack 2;

[0044] The limiting member 5 is suitable for maintaining the distance between the two bearing frames 2. The lengths of the two bearing frames 2 are slightly shorter than the side lengths of the steel pipe frame 1. Therefore, when the single bearing frame 2 is connected to the steel pipe frame 1 by two steel cables 3, the two steel cables 3 are both inclined, thereby effectively reducing the lateral tension of the bearing frame 2, effectively avoiding shaking when the two bearing frames 2 are hoisting a number of rail sleeper members 31, and improving the stability of the hoisting process of the bearing frames 2; and by setting the steel pipe frame 1 in conjunction with a number of steel cables 3, a certain distance can be made between the two bearing frames 2, and then when the two bearing frames 2 of the lifting belt move down and approach a number of rail sleeper members 31, the two bearing frames 2 can be placed at both ends of the number of rail sleeper members 31, thereby facilitating the staff to directly complete the bearing support of the two bearing frames 2 on the two ends of the number of rail sleeper members 31, effectively improving the two bearing members on the number of rail sleeper members 31, thereby improving the load-bearing effect of several rail sleeper parts 31, and thus improving the lifting efficiency of several rail sleeper parts 31; and through the two positioning components 4, the stability of several rail sleeper parts 31 after being placed on two bearing frames 2 can be improved, and several rail sleeper parts 31 can be separated, so that two adjacent rail sleeper parts 31 are not easy to contact each other during the lifting process, thereby avoiding damage caused by collision between the rail sleeper parts 31 during the lifting process; at the same time, during the lifting process, since several steel cables 3 are in a relatively vertical state, the protection components 6 arranged at the annular rings 30 at the upper and lower ends of the steel cables 3 can effectively isolate the direct contact between the steel cables 3 and the steel pipe frame 1 and the bearing frame 2, and thus can effectively protect the steel cables 3, reduce the wear and tear of the steel cables 3, increase the service life of the steel cables 3, avoid frequent replacement of the steel cables 3, and reduce the safety hazards generated during lifting.

[0045] Optionally, the positioning assembly 4 includes two control grooves 7 symmetrically opened on the carrier 2, a pressure rod 8 slidably arranged in the two control grooves 7 at both ends, two guide rods 9 movably mounted at both ends of the pressure rod 8, two return springs 10 movably sleeved on the two guide rods 9, two positioning screws 11 symmetrically spirally mounted on the carrier 2, and a plurality of positioning blocks 12 fixedly connected to the bottom of the pressure rod 8;

[0046] The two guide rods 9 are respectively fixed in the two control grooves 7;

[0047] The lower ends of the two positioning screws 11 are both against the upper surface of the pressing rod 8;

[0048] The two ends of the two return springs 10 are respectively fixedly connected to the inner walls of the two control grooves 7 and the lower surfaces of the two ends of the pressure rod 8. When the two bearing frames 2 complete the bearing of the two ends of the plurality of rail sleepers 31, the provided pressure rod 8 can limit the upper ends of the plurality of rail sleepers 31, and through the provided plurality of positioning blocks 12, the horizontal movement of the plurality of rail sleepers 31 can be limited, thereby improving the stability of the bearing of the bearing frame 2 on the plurality of rail sleepers 31, and avoiding the collision between the plurality of rail sleepers 31 during the hoisting process and causing damage, and the rail sleepers 31 at different heights can be prevented from being damaged. When hoisting, the positioning screws 11 at both ends of the carrier frame 2 can be rotated to push the two ends of the pressure rod 8 to move in the two control grooves 7 respectively, and make the pressure rod 8 move up and down. The two guide rods 9 provided can improve the stability of the pressure rod 8 in the control groove 7. Under the elastic force of the two return springs 10, the pressure rod 8 can always be pushed to conflict with the two positioning screws 11, thereby ensuring the space between the pressure rod 8 and the carrier frame 2, making it convenient to place one end of a plurality of rail sleeper members 31 between the carrier frame 2 and the pressure rod 8, thereby completing the restriction of a plurality of rail sleeper members 31.

[0049] Optionally, the protection assembly 6 includes a wear-resistant seat 16 sleeved outside the annular ring 30, a fixing block 17 hinged on the wear-resistant seat 16, and an elastic clamping block 18 fixed on the wear-resistant seat 16, wherein

[0050] By rotating the fixing block 17, the fixing block 17 gradually approaches the elastic block 18, and the two wear-resistant seats 16 in the upper and lower end protection components 6 of the single steel cable 3 will contact the steel pipe frame 1 and the bearing frame 2 respectively, thereby avoiding the direct contact between the annular rings 30 at the upper and lower ends of the steel cable 3 and the steel pipe frame 1 and the bearing frame 2, so that when a plurality of rail sleeper members 31 are hoisted, the steel cable 3 can be effectively protected and the wear of the steel cable 3 can be reduced. After the wear-resistant seat 16 has been used for a period of time, the elastic block 18 on the wear-resistant seat 16 can be pressed to deform it and contact the limit of the fixing block 17. At this time, By rotating the fixing block 17, the connection between the wear-resistant seat 16 and the annular ring 30 is released, and then a new wear-resistant seat 16 can be taken and mounted on the annular ring 30, and the fixing block 17 is rotated so that the fixing block 17 approaches and squeezes the elastic clamping block 18. When the fixing block 17 contacts the annular ring 30, the elastic clamping block 18 limits the position of the fixing block 17, thereby completing the connection between the wear-resistant seat 16 and the annular ring 30. The overall wear-resistant seat 16 is easy to disassemble and assemble, and can be directly replaced after the wear-resistant seat 16 has been used for a period of time, so as to ensure the protection of the annular rings 30 at both ends of the steel cable 3 and effectively improve the service life of the steel cable 3.

[0051] Optionally, the limiting member 5 includes two clamping rods 13 respectively fixed on one end of the two supporting frames 2, a limiting rod 14 arranged on one end of the two supporting frames 2, and two clamping grooves 15 opened on the limiting rod 14;

[0052] The two clamping rods 13 are respectively interference fit with the two clamping grooves 15. When the two supporting frames 2 complete the load-bearing support of the plurality of rail sleeper components 31, the limiting rod 14 can be used to connect the two clamping rods 13 on the two supporting frames 2 through the two clamping grooves 15 thereon, thereby limiting the distance between the two supporting frames 2. Through the two limiting components 5, the positions of both ends of the two supporting frames 2 can be effectively limited, thereby effectively ensuring the stability of the two supporting frames 2 when hoisting the plurality of rail sleeper components 31 and increasing the safety during hoisting.

[0053] Optionally, the bearing frame 2 includes two side plates 19 respectively connected to the lower ends of two of the steel cables 3, an angle steel 20 connected between the two side plates 19, two assembly grooves 21 respectively opened on the two side plates 19, and two damping bearings 22 respectively installed in the two assembly grooves 21;

[0054] The annular ring 30 at the lower end of one of the steel cables 3 is sleeved on one of the damping bearings 22;

[0055] The two side plates 19 are both provided with a control groove 7, and the two side plates 19 are both spirally mounted with a positioning screw 11;

[0056] The two side panels 19 are fixedly connected to the opposite sides with a clamping rod 13. When the two side panels 19 are in a vertical state due to gravity, the angle steel 20 between the two side panels 19 is in a V-shaped state, and then when a number of steel cables 3 pull the two angle steels 20 on the two supporting frames 2 to support the two ends of a number of rail sleepers 31, the several side panels 19 are all in an inclined state, so that the side panels 19 on the two supporting frames 2 tend to approach each other, and then the two angle steels 20 can be approached to each other, effectively supporting the several rail sleepers 31; and because the annular ring 30 at the lower end of the steel cable 3 is connected to the side panel 19 through the damping bearing 22, when the side panel 19 rotates, the wear caused by the side panel 19 on the annular ring 30 at the lower end of the steel cable is effectively reduced.

[0057] Optionally, the steel pipe rack 1 includes a hoisting steel plate 23 connected to an external crane, two brackets 24 symmetrically connected to both sides of the hoisting steel plate 23, a rectangular frame 25 connected to the bottom of the two brackets 24, a connecting pipe 26 disposed in the rectangular frame 25 and connected to the bottom of the hoisting steel plate 23, and a plurality of clamping members 27 fixed to the four corners of the upper end of the rectangular frame 25;

[0058] The locking member 27 is composed of two locking rods 28 screwed on the rectangular frame 25;

[0059] The annular ring 30 at the upper end of one of the steel cables 3 is placed between two of the clamping rods 28. When in use, the hook of the external crane is connected to the lifting steel plate 23, and the annular rings 30 at the upper ends of the plurality of steel cables 3 are respectively sleeved on the four corners of the rectangular frame 25, and the annular rings 30 at the upper ends of the plurality of steel cables 3 are respectively placed between two clamping rods 28 in the plurality of clamping members 27, so that the two clamping rods 28 can limit the steel cables 3 to prevent the steel pipe frame 1 from moving when the two bearing frames 2 are lifted by the plurality of steel cables 3. The steel cables 3 are detached from the steel pipe frame 1, thereby ensuring the stability of the plurality of rail sleeper components 31 during hoisting and avoiding safety hazards. The rectangular frame 25 is set to control the distance between the plurality of steel cables 3, so that there is a certain distance between the two support frames 2. Then, when hoisting the plurality of rail sleeper components 31, the two support frames 2 are hoisted downward and can be directly placed at the two ends of the plurality of rail sleeper components 31, thereby facilitating the two support frames 2 to carry the two ends of the plurality of rail sleeper components 31, facilitating the operation of the staff, and effectively improving the hoisting efficiency.

[0060] Optionally, a plurality of reinforcing wing plates 29 are fixedly connected between the two brackets 24 and the rectangular frame 25. By setting the plurality of reinforcing wing plates 29, the stability of the connection between the two brackets 24 and the rectangular frame 25 can be improved, thereby ensuring the safety of the steel pipe rack 1 when in use.
