Description

Technical Field

[0001] The utility model relates to the technical field of subway construction, in particular to 500kV high-voltage line subway construction hoisting equipment. Background Art

[0002] Gantry cranes are commonly used in subway construction. These cranes consist of a beam and columns, move on rails, and have a high lifting capacity. They are widely used in ports, freight yards, shipyards, power stations, and other locations, offering high site utilization, a large operating range, wide adaptability, and strong versatility.

[0003] Due to the large size of conventional gantry cranes, they need to ensure that there are no obstacles around them during movement to avoid unnecessary structural collisions. However, since the surface of their self-propelled trolleys does not have structural protection, once a structural collision occurs, the damage caused is relatively large. Under the 500kV high-voltage line, the equipment, functions and mobile space of conventional gantry cranes are limited, making it difficult to meet the lifting operation requirements of subway construction.

[0004] In view of the above shortcomings, this application proposes a 500kV high-voltage line subway construction hoisting equipment. Utility Model Content

[0005] The purpose of the utility model is to provide a 500kV high-voltage line subway construction hoisting device to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A 500kV high-voltage line subway construction hoisting equipment includes a beam assembly and a crane group. The crane group is installed on the top of the beam assembly, and a long support leg is installed at one end of the bottom of the beam assembly. A short support leg is installed at the end of the bottom of the beam assembly away from the long support leg, and a walking trolley is installed at the bottom of both the short support leg and the long support leg. At the same time, a self-propelled track is laid on the bottom of the walking trolley, and an anti-collision plate is installed on the side surface of the walking trolley.

[0008] Furthermore, the beam frame assembly includes a main beam, end beams and a movable track. The end beams are installed on both sides of the main beam, and the top surface of the end beam is paved with a movable track.

[0009] Furthermore, the main beam and the end beam are connected and fixed by anchor bolts, and the movable rail is horizontally fixedly installed on the top surface of the end beam.

[0010] Furthermore, the lifting vehicle group includes a self-propelled trolley, a winch, a hoisting hoist and a self-locking hook. The winch is installed on the top of the self-propelled trolley, and the hoisting hoist is connected to the bottom of the winch, and the self-locking hook is connected to the bottom of the hoisting hoist.

[0011] Furthermore, the bottom wheel structure of the self-propelled trolley is slidably connected to the movable track, and the hoisting hoist, the winch and the self-locking hook are connected to each other through cables.

[0012] Furthermore, the long legs and short legs are fixed to the bottom ends of the beam assembly using rectangular flange structures and anchor bolts, and the long legs and short legs are fixed to the top ends of the walking trolley using rectangular flange structures and anchor bolts.

[0013] Furthermore, the walking trolley includes a trolley body, support piles, support wheels and a drive motor. Support piles are installed at both ends of the top of the trolley body, and support wheels are installed inside the trolley body, and a drive motor is installed at one end of the support wheel through a coupling.

[0014] Furthermore, the bottom ends of the long legs and the short legs are connected and fixed to the top ends of the support piles, and the surface structure of the support wheels matches the surface structure of the self-propelled track.

[0015] The utility model has the following beneficial effects:

[0016] 1. A crane assembly is installed on the top of the beam assembly, wherein the self-propelled trolley is installed on the surface of the moving track at the top of the end beam, so that the entire crane assembly can be horizontally translated left and right along the surface of the moving track, and the walking trolley installed at the bottom of the long legs and short legs, under the operation of the drive motor, drives the support wheels connected thereto, and can be horizontally translated forward and backward along the self-propelled track laid at the bottom. The use of the above structure can ensure the operational flexibility of the entire device to ensure that the construction needs are met. At the same time, the long legs and short legs symmetrically installed front and back at the bottom of the beam assembly can also ensure that the entire lifting equipment has sufficient structural support, so as to ensure that heavier materials have good stability and support during the lifting process.

[0017] 2. By installing a self-locking hook under the lifting hoist and utilizing the locking structure of the self-locking hook itself, it is possible to prevent the lifting lug or cable from being hung on the self-locking hook during the process of lifting materials by the crane group, thereby preventing unnecessary structural detachment, thereby causing construction accidents. This is also to avoid unnecessary personal injury and damage to materials. In addition, by installing anti-collision plates on the surface of the walking trolley installed at the bottom of the long legs and short legs, it is possible to minimize the damage caused by structural collision or damage to the walking trolley itself during the movement of the entire equipment, thereby playing a good structural protection role.

[0026] like Figures 1 to 3As shown, the 500kV high-voltage line subway construction hoisting equipment of the present invention includes a beam assembly 1 and a crane group 2. The crane group 2 is installed on the top of the beam assembly 1, and a long support leg 3 is installed at one end of the bottom of the beam assembly 1, and a short support leg 4 is installed at the end of the bottom of the beam assembly 1 away from the long support leg 3, and a walking trolley 5 is installed at the bottom of the short support leg 4 and the long support leg 3. At the same time, a self-propelled track 6 is laid on the bottom of the walking trolley 5, and an anti-collision plate 7 is installed on the side surface of the walking trolley 5.

[0027] In some embodiments, the beam frame assembly 1 includes a main beam 101, an end beam 102 and a movable track 103. The end beams 102 are installed on both sides of the main beam 101, and the movable track 103 is laid on the top surface of the end beam 102. The main beam 101 and the end beam 102 are connected and fixed by anchor bolts, and the movable track 103 is horizontally fixed on the top surface of the end beam 102.

[0028] The lifting vehicle group 2 includes a self-propelled trolley 201, a winch 202, a hoisting hoist 203 and a self-locking hook 204. The winch 202 is installed on the top of the self-propelled trolley 201, and the hoisting hoist 203 is connected to the bottom of the winch 202, and the self-locking hook 204 is connected to the bottom of the hoisting hoist 203. The bottom wheel structure of the self-propelled trolley 201 is slidably connected to the moving track 103, and the hoisting hoist 203, the winch 202 and the self-locking hook 204 are connected to each other by cables.

[0029] It can be understood that the self-propelled trolley 201 is installed on the surface of the moving track 103 at the top of the end beam 102, so that the entire lifting vehicle group 2 can be translated left and right in the horizontal direction along the surface of the moving track 103, and the walking trolley 5 installed at the bottom of the long support leg 3 and the short support leg 4, under the operation of the drive motor 504, drives the support wheel 503 connected to it, and can be translated forward and backward in the horizontal direction along the self-propelled track 6 laid at the bottom.

[0030] During the specific design, the long legs 3 and the short legs 4 can be fixed to the bottom ends of the beam assembly 1 using rectangular flange structures and anchor bolts, and the long legs 3 and the short legs 4 can be fixed to the top ends of the walking trolley 5 using rectangular flange structures and anchor bolts.

[0031] In some embodiments, the traveling trolley 5 includes a trolley body 501, support piles 502, support wheels 503 and a drive motor 504. Support piles 502 are installed at both ends of the top of the trolley body 501, and support wheels 503 are installed inside the trolley body 501. One end of the support wheel 503 is installed with a drive motor 504 through a coupling.

[0032] Among them, the bottom ends of the long legs 3 and the short legs 4 are both connected and fixed to the top of the support pile 502, and the surface structure of the support wheel 503 matches the surface structure of the self-propelled track 6. The self-locking hook 204 itself has a lockable structure, so that in the process of lifting materials using the lifting vehicle group 2, unnecessary structure detachment is prevented when the lifting ear or cable is hung on the self-locking hook 204.

[0033] When using the above-mentioned 500kV high-voltage line subway construction hoisting equipment, the driving motor 504 first drives the support wheel 503 connected thereto to move horizontally along the surface of the self-propelled track 6. During this process, the long legs 3 and short legs 4 connected to the top of the support piles 502 at both ends of the trolley body 501 cooperate with the structural arrangement of the beam assembly 1 to ensure that the material maintains sufficient stability during the hoisting process;

[0034] The self-propelled trolley 201 is driven to move horizontally left and right along the surface of the movable track 103 installed on the top of the end beam 102. Then, under the operation of the winch 202, the hoisting hoist 203 and the self-locking hook 204 connected by cables below can be raised and lowered in the vertical direction to meet the needs of use.

[0035] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms.
