Technical Field

[0001] The invention relates to the technical field of flexible steel shed hole hoisting, and in particular to flexible steel shed hole hoisting equipment. Background Art

[0002] Flexible steel shed tunnel is a steel structure plus flexible protection net system mainly used for tunnel entrances and exits and high slope roadbed protection against falling rocks. It is mainly composed of steel structure rigid frame and flexible protection net. The steel structure rigid frame is the main structure, responsible for supporting and fixing the entire system, while the flexible protection net is used as a rockfall protection layer, using the characteristics of "softness overcoming hardness" to resist the impact of falling rocks.

[0003] Traditional flexible steel sheds use cranes as the main lifting and handling equipment. The cranes work with special flexible steel shed fixtures to lift the entire structure or components of the flexible steel shed from the ground and move them to the predetermined position.

[0004] However, the traditional flexible steel shed hole clamp has the problem of inconvenient installation during the clamping process of the flexible steel shed hole. This is because the shapes and specifications of the traditional flexible steel shed holes are not exactly the same. Therefore, when using special clamps to clamp and fix the flexible steel shed holes, it is necessary to constantly adjust the shape and position of the clamp to meet the effective limit fixation of flexible steel shed holes of different shapes and specifications, so there is a problem of inconvenient installation.

[0009] Furthermore, the interiors of the two bases are hollow in design, and a first hydraulic cylinder is vertically fixedly installed at the center of the bottom of the inner cavity of the two bases. The output ends of the two first hydraulic cylinders pass through the base and are fixedly connected to the corresponding first telescopic rods.

[0010] Furthermore, second hydraulic cylinders are obliquely installed on both sides of the two first hydraulic cylinders, and output ends of the four second hydraulic cylinders pass through the base and are fixedly connected to the corresponding second telescopic rods.

[0011] Furthermore, a motor with an output end fixedly connected to one end of a double-headed screw is vertically fixedly installed on the outer side wall of one of the first telescopic rods, a limit ring is fixedly mounted on the center of the outer rod wall of the double-headed screw, and an annular groove matching the limit ring is opened on the inner tube wall of the support tube. The support tube is rotatably mounted on the double-headed screw through the annular groove and the limit ring.

[0012] Furthermore, first connectors are fixedly installed on both sides of the two threaded seats, second connectors are fixedly installed on one side of the four guide seats close to the corresponding threaded seats, and both ends of the four extrusion rods are rotatably installed with the corresponding first connectors and second connectors respectively.

[0013] Furthermore, threaded holes are provided on both of the extrusion parts, both ends of the double-headed screw rod are threaded through the corresponding threaded holes, two limiting circular holes are provided on both of the extrusion seats, and the two guide rods are respectively provided through the corresponding limiting circular holes, and the inner diameter of the limiting circular hole is larger than the outer diameter of the guide rod.

[0014] Furthermore, two opposite outer side walls of the two top seats are provided with sliding grooves, and installation cavities are provided in the two top seats. Both ends of the two pressing rods pass through the corresponding sliding grooves and extend into the corresponding installation cavities respectively.

[0015] Furthermore, the bottom ends of the two lower pressure rods are vertically fixed with extrusion seats, the bottoms of the two extrusion seats are provided with rotating openings, and extrusion rollers are arranged below the two extrusion seats, and the two extrusion rollers are rotatably installed in the corresponding extrusion seats respectively.

With the support of the double-headed screw and the guide rod, as well as the squeezing of the two ends of the squeezing assembly and the squeezing seat, the flexible steel shed hole can be quickly limited and fixed, thereby improving the stability of the flexible steel shed hole during the overall hoisting and transportation process.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The present invention will be further described below in conjunction with the embodiments.

[0039] Embodiment 1:

[0040] Reference Figure 1-8 , which is the first embodiment of the present invention, a flexible steel shed hole hoisting device comprises two parallel bases 1, a first telescopic rod 12 is telescopically and slidably installed directly above the two bases 1, and a second telescopic rod 14 is telescopically and slidably installed on both sides of the two bases 1. The adjustment component comprises a double-headed screw 16 rotatably installed between the two first telescopic rods 12, a support cylinder 18 is rotatably sleeved on the center of the double-headed screw 16, and also comprises guide rods 19 on both sides of the double-headed screw 16, two guide rods 19, and two extrusion components each comprise a threaded seat 21 threadedly sleeved on the double-headed screw 16, and also comprise a sliding seat 21 respectively. The guide seat 22 is rotatably mounted on the guide rod 19, and an extrusion rod 23 is rotatably mounted between the threaded seat 21 and the corresponding guide seat 22. The design purpose of the guide seat 22 is to ensure that the extrusion rod 23 always maintains a connection relationship with the threaded seat 21, and the design purpose of the extrusion rod 23 is to ensure that no matter the double-headed screw 16 and the guide rods 19 on both sides are telescopically slid to any height, the threaded seat 21 and the guide seats 22 on both sides always maintain a connection relationship, that is, the threaded seat 21 can only reciprocate along the axial direction of the double-headed screw 16, and will not rotate synchronously. At this time, the guide seat 22 has a limiting effect on the threaded seat 21;

[0041] The two extrusion pieces 3 are respectively threadedly mounted on the two ends of the double-headed screw rod 16. Both sides of the two extrusion pieces 3 are penetrated with spiral holes for convenient threading on the double-headed screw rod 16, and are respectively located on the opposite sides of the two threaded seats 21. The two top seats 4 are respectively vertically fixedly mounted on the top of the corresponding base 1. A lower pressure rod 41 is installed between the two top seats 4 for lifting and sliding. The lifting assembly includes two first tooth plates 51 above the two top seats 4 for lifting and sliding. A hook 53 is installed between two adjacent first tooth plates 51. When the hook 53 is lifted by a lifting device such as a crane, it will pull the two first tooth plates 51 to slide upward at the same time;

[0042] And because the first tooth plate 51 is limitedly slidably inserted into the corresponding top seat 4, the sliding of the first tooth plate 51 is stable and reliable and will not deviate, thereby improving the stability of the lifting process, and the four first tooth plates 51 are meshed with gears 54 at the bottom, and the second tooth plates 55 are meshed with the other side of the four gears 54. The first tooth plates 51 and the second tooth plates 55 are distributed symmetrically about the gear 54, and the four second tooth plates 55 are respectively detachably installed with the corresponding lower pressure rods 41. That is to say, the lower pressure rod 41 including the extrusion seat 42 and the extrusion roller 43 can be removed from the two top seats 4 as a whole, which is convenient for the installation of the flexible steel shed hole and the disassembly between the lifting equipment and the flexible steel shed hole.

[0043] Embodiment 2:

[0044] Reference Figure 1-4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the interiors of the two bases 1 are both hollow in design, and the first hydraulic cylinders 11 are vertically fixedly installed at the center of the inner cavity bottom of the two bases 1. The output ends of the two first hydraulic cylinders 11 penetrate the base 1 and are fixedly connected to the corresponding first telescopic rods 12. Second hydraulic cylinders 13 are obliquely installed on both sides of the two first hydraulic cylinders 11. The output ends of the four second hydraulic cylinders 13 penetrate the base 1 and are fixedly connected to the corresponding second telescopic rods 14. Figure 3 It can be known that the first hydraulic cylinder 11 and the two second hydraulic cylinders 13 are radially distributed, and the two second hydraulic cylinders 13 are axially symmetrically distributed with respect to the first hydraulic cylinder 11;

[0045] A motor 15 whose output end is fixedly connected to one end of a double-headed screw 16 is vertically fixedly installed on the outer side wall of one of the first telescopic rods 12. A limit ring 17 is fixedly mounted at the center of the outer rod wall of the double-headed screw 16. An annular groove matching the limit ring 17 is opened on the inner cylinder wall of the support tube 18. The support tube 18 is mounted on the double-headed screw 16 through the annular groove and the limit ring 17. Therefore, when the inner arc wall of the flexible steel shed hole and the support tube 18 are released, the weight of the flexible steel shed hole is converted into static friction on the support tube 18, so that when the starting motor 15 drives the double-headed screw 16 to rotate, the support tube 18 can be kept stationary through the limit rotation of the limit ring 17 and the double-headed screw 16, avoiding the double-headed screw 16 from contacting the inner arc wall of the flexible steel shed hole, thereby avoiding the inner arc wall of the flexible steel shed hole being damaged by friction after the double-headed screw 16 rotates.

[0046] The remaining structures are the same as those of Example 1.

[0047] Embodiment 3:

[0048] Reference Figure 4-6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: first connectors are fixedly installed on both sides of the two threaded seats 21, and second connectors are fixedly installed on the four guide seats 22 close to the corresponding threaded seats 21. The two ends of the four extrusion rods 23 are rotatably installed with the corresponding first connectors and second connectors respectively. The extrusion rods 23 complete the linkage between the threaded seat 21 and the guide seat 22. Regardless of whether the double-headed screw 16 and the guide rods 19 on both sides are telescopically slid to any height, the threaded seat 21 and the guide seats 22 on both sides always maintain a connection relationship, that is, the threaded seat 21 can only reciprocate along the axial direction of the double-headed screw 16, and there will be no synchronous rotation. At this time, the guide seat 22 has a limiting effect on the threaded seat 21;

[0049] A threaded hole 31 is penetrated through the two extrusion pieces 3, and both ends of the double-headed screw rod 16 are threaded through the corresponding threaded holes 31 respectively. Two limiting circular holes 32 are penetrated through the two extrusion pieces 3, and the two guide rods 19 are penetrated through the corresponding limiting circular holes 32 respectively. The inner diameter of the limiting circular hole 32 is larger than the outer diameter of the guide rod 19. The reason why the inner diameter of the limiting circular hole 32 needs to be larger than the outer diameter of the guide rod 19 is that the double-headed screw rod 16 and the two guide rods 19 will have different degrees of telescopic adjustment. Therefore, the distance between the double-headed screw rod 16 and the two guide rods 19 will change. Therefore, the guide rod 19 will also be forced to adjust the relative position with the extrusion piece 3, but it is necessary to limit the extrusion piece 3 through the limiting circular hole 32 and the guide rod 19 to ensure that the extrusion piece 3 will only slide back and forth along the axial direction of the double-headed screw rod 16 when the double-headed screw rod 16 rotates.

[0050] The remaining structure is the same as that of Example 2.

[0051] Embodiment 4:

[0052] Reference Figure 1 , 7 -8 is the fourth embodiment of the present invention, which is different from the third embodiment in that: two opposite outer side walls of the two top seats 4 are provided with slide grooves 44, and installation cavities are provided in the two top seats 4. The two ends of the two lower pressure rods 41 respectively penetrate the corresponding slide grooves 44 and extend into the corresponding installation cavities. The bottom ends of the two lower pressure rods 41 are vertically fixed with extrusion seats 42. The bottoms of the two extrusion seats 42 are provided with rotation openings. Extrusion rollers 43 are provided below the two extrusion seats 42. The two extrusion rollers 43 are rotatably installed in the corresponding extrusion seats 42. The reason why the extrusion rollers 43 are provided in a cylindrical shape and can rotate is to avoid collision and damage of the extrusion rollers 43 during the initial contact with the flexible steel shed hole.

[0053] The four gears 54 are all rotatably installed in the corresponding installation cavities. The tops of the two top seats 4 are both penetrated through the installation cavities and are provided with two insertion holes. The four first tooth plates 51 are respectively adapted to penetrate the insertion holes and are meshed and installed with the corresponding gears 54. A fixing rod 52 is vertically fixedly installed between two adjacent first tooth plates 51. Two hooks 53 are respectively fixedly welded to the tops of the corresponding fixing rods 52. When the flexible steel shed hole is hoisted to the designated work station, the bottom of the flexible steel shed hole contacts the ground. The pressing rod 41, the extrusion seat 42 and the extrusion roller 43 can be disassembled from the top seat 4. At this time, the height of the top seat 4 and the base 1 can be lowered to separate the hoisting equipment from the bottom of the flexible steel shed hole to complete the disassembly.

[0054] The four second tooth plates 55 are respectively lifted and slidably installed in the corresponding installation cavities. Plugs are vertically fixedly installed on the four second tooth plates 55 near the corresponding lower pressure rods 41. Both ends of the two lower pressure rods 41 are provided with slots for convenient plugging of the plugs. The width of the lower pressure rod 41 is consistent with the width of the corresponding slide groove 44, and the width of the second tooth plate 55 is greater than the width of the slide groove 44. When the lower pressure rod 41 passes through the slide groove 44 and extends into the installation cavity, and completes the detachable insertion with the second tooth plate 55 through the slot and the plug, it will temporarily form a whole with the second tooth plate 55. When the second tooth plate 55 is forced to descend in height, it will drive the lower pressure rod 41 to descend in height synchronously.

[0055] The remaining structure is the same as that of Example 3.

[0056] Working principle of the present invention:

[0057] In the first step, the two bases 1 are placed on the ground, and at this time, the lifting equipment such as a crane has not yet been lifted and fixed with the two hooks 53;

[0058] The second step is to place the flexible steel shed hole to be lifted above the two guide rods 19 and the support tube 18. At this time, since the support tube 18 and the two guide rods 19 are not adjusted, they will not all fit with the inner arc wall of the flexible steel shed hole. At this time, the first hydraulic cylinder 11 and the second hydraulic cylinder 13 can be started to push the corresponding first telescopic rod 12 or the second telescopic rod 14 respectively, so as to adjust the setting height of the double-headed screw 16, that is, the support tube 18 and the two guide rods 19, so that the support tube 18 and the two guide rods 19 are finally fit with the inner arc wall of the flexible steel shed hole, thereby improving the supporting effect of the flexible steel shed hole;

[0059] The third step is to start the motor 15 to drive the double-headed screw 16 to rotate. Since the support tube 18 is in contact with the arc wall inside the flexible steel shed hole at this time, the gravity of the flexible steel shed hole is converted into static friction, resulting in the support tube 18 remaining stationary when the double-headed screw 16 rotates. The support tube 18 blocks the double-headed screw 16 from sliding and wearing against the arc wall inside the flexible steel shed hole. With the rotation of the double-headed screw 16, the two threaded seats 21 and the two extrusion members 3 are driven to approach and finally squeeze and contact the two ends of the flexible steel shed hole, completing the extrusion and fixation of the flexible steel shed hole, making the flexible steel shed hole more stable and reliable during the hoisting process.

[0060] The fourth step is to pass the two ends of the two lower pressure rods 41 through the corresponding slide grooves 44 respectively, extend them into the corresponding installation cavities, and align the slots at the ends of the lower pressure rods 41 with the corresponding plugs, and finally make the lower pressure rods 41 and the corresponding second toothed plates 55 plugged and firmly connected. At this time, the hook of the crane is hung on the two hooks 53, and then the hooks 53, that is, the corresponding two first toothed plates 51, are lifted upward by the crane. At this time, the first toothed plates 51 are engaged to drive the gears 54 to rotate, and the gears 54 are engaged to drive the second toothed plates 55 to move vertically downward synchronously, so that the extrusion seat 42 and the corresponding extrusion roller 43 are driven downward by the lower pressure rod 41 until the extrusion roller 43 is squeezed and collides with the outer arc wall of the flexible steel shed hole. At this time, the second toothed plate 55 cannot continue to descend, and the gear 54 cannot rotate, and the corresponding first toothed plate 51 cannot rise any more. By continuing to lift upward by the crane, the two top seats 4 and the two bases 1 including the flexible steel shed hole will rise synchronously. At this time, the flexible steel shed hole leaves the ground and is conveniently lifted to the designated support station.

[0061] In the fifth step, through the combination of gear 54 and tooth plate, the extrusion roller 43 originally located above the flexible steel shed hole is squeezed downward to contact the flexible steel shed hole, and the support of the support tube 18 and the guide rod 19, as well as the extrusion assembly and the extrusion part 3 at both ends are used to complete the rapid limiting and fixing of the flexible steel shed hole, thereby improving the stability of the flexible steel shed hole during the overall lifting and transportation process. When the flexible steel shed hole is lifted to the designated work station, it is also convenient to quickly disassemble the lifting equipment from the crane and the flexible steel shed hole.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
