Description

Technical Field

[0001] The utility model belongs to the field of gantry cranes, and in particular relates to an indoor gantry crane capable of carrying people for operation. Background Art

[0002] Sometimes when processing heavy products in the workshop, such as tonnage-level products, in order to facilitate the transfer of products between various workstations, gantry cranes are usually used to hoist the products. In order to allow the gantry crane to have enough hoisting space, the floor height of the corresponding workshop is generally made relatively high, which makes its ceiling relatively high. When the equipment installed on the top of the workshop is broken and needs to be replaced or repaired, it is often necessary to transport a boom-type aerial work vehicle from other locations, and people use the boom-type aerial work vehicle to climb up for repair, which is time-consuming and labor-intensive. Utility Model Content

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the problem that the current workshops with gantry cranes often have high floor heights, and it is necessary to transport a boom-type aerial work vehicle from other places to repair or replace the equipment on the workshop ceiling, which is time-consuming and labor-intensive.

[0004] In order to solve the above technical problems, the utility model provides an indoor gantry crane that can carry people for operation, including a load-bearing main beam and a work vehicle, the work vehicle is slidably connected to the load-bearing main beam through a guide mechanism, and can automatically slide along the length extension direction of the load-bearing main beam, the work vehicle includes a standing platform and three guardrails, the standing platform is located above the load-bearing main beam and parallel to the load-bearing main beam, and the three guardrails are vertically fixed on the three edges of the standing platform.

[0005] Furthermore, it also includes a tool box, which is fixed on one of the guardrail plates and has an opening on the top.

[0006] Furthermore, the height of the guardrail is greater than or equal to the average center of gravity height of an adult.

[0007] Furthermore, the work vehicle also includes at least four sliding wheels, each of which is connected to the bottom of the standing platform through a connecting frame, the connecting frame is fixed to the standing platform, the sliding wheel is rotatably connected to the connecting frame, and a motor is also fixed on each connecting frame. The output shaft of each motor is coaxially fixed to the corresponding sliding wheel, and the circumferential surface of the sliding wheel is in contact with the top surface of the load-bearing main beam.

[0008] Furthermore, the guide mechanism includes two oppositely arranged clamping plates and two reinforcement frames. The tops of the two clamping plates are respectively connected to two oppositely arranged guardrails in one piece, and are respectively clamped on two side surfaces of the load-bearing main beam where the long sides are provided. Each of the reinforcement frames is mounted on and tightened the standing platform, the clamping plates and the load-bearing main beam.

[0009] The technical solution of the utility model has the following beneficial effects:

[0010] The utility model connects a work vehicle by sliding on the load-bearing main beam of the gantry crane. Workers enter the work vehicle and can control the work vehicle to move along the length direction of the load-bearing main beam with a remote control, so as to send the workers to the desired place in the X-axis direction. The gantry (load-bearing main beam) of the crane can move along the Y-axis, thereby driving the work vehicle on the load-bearing main beam to move along the Y-axis. The load-bearing main beam itself is very high, and the work vehicle can make people climb up to work with the help of the height of the load-bearing main beam. The work vehicle can adjust its position along the X-axis and Y-axis directions, so as to reach the desired location conveniently. When using the utility model to repair workshops with higher floors, there is no need to transport a crank arm work vehicle from other places, which saves equipment purchase costs, manpower and time.

DETAILED DESCRIPTION

[0016] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] The utility model provides an indoor gantry crane capable of carrying people for operation, comprising a load-bearing main beam 1 and a work vehicle 2. The work vehicle 2 is slidably connected to the load-bearing main beam 1 through a guide mechanism 23, and can automatically slide along the length extension direction of the load-bearing main beam 1. The work vehicle 2 comprises a standing platform 21 and three guardrails 22. The standing platform 21 is located above the load-bearing main beam 1 and is parallel to the load-bearing main beam 1. The three guardrails 22 are vertically fixed on three edges of the standing platform 21.

[0021] When it is necessary to repair or replace the appliances (electric lights, fans, etc.) on the indoor ceiling, the worker can climb up the load-bearing main beam 1 with the support feet of the indoor gantry crane, enter the work vehicle from the side where the work vehicle is not provided with the guardrail 22, and manually control the remote control by the worker to control the work vehicle to slide along the length direction of the load-bearing main beam 1 (i.e., the X-axis direction), so as to send the worker to the desired position, and the movement in the Y-axis direction only depends on the gantry of the gantry crane itself to move along the Y-axis. Since the load-bearing main beam 1 is part of the gantry, when the gantry moves, it naturally drives the work vehicle 2 to move. The signal output end of the remote control is wirelessly connected to the signal input end of the driving mechanism of the work vehicle 2. The work vehicle 2 can allow people to work at heights by relying on the height of the load-bearing main beam 1.

[0022] In order to facilitate replacement and maintenance, the utility model further includes a tool box 3, which is fixed on one of the guardrails 22, and has an opening 31 on the top. Tools of various types and specifications are placed in the tool box 3. Every time a worker repairs or replaces an instrument, he can directly take the required tools from the tool box 3, which prevents the worker from having to carry a lot of tools up before each operation, thus preventing the worker from being too tired and also preventing the tool from falling from a height when the worker is climbing with the tools, thereby ensuring safety.

[0023] The standing platform 21 is for workers to stand on, and the guardrail 22 is to prevent workers from falling from a height. In order to make the guardrail truly play a protective role, the height of the guardrail 22 is greater than or equal to the average center of gravity height of an adult. In this way, workers are generally not likely to fall over the guardrail 22.

[0024] The work vehicle 2 of the utility model can move itself by sliding the sliding wheel 4 at the bottom on the top surface of the load-bearing main beam 1. The work vehicle 2 includes at least four sliding wheels 4, and of course more than four can be provided. The sliding wheel 4 is connected to the bottom of the standing platform 21 through a connecting frame 5, the connecting frame 5 is fixed to the standing platform 21, and the sliding wheel 4 is rotatably connected to the connecting frame 5. A motor 6 is also fixed on each connecting frame 5, and the output shaft of each motor 6 is coaxially fixed with the corresponding sliding wheel 4, and the circumferential surface of the sliding wheel 4 is in contact with the top surface of the load-bearing main beam 1. When the output shaft of the motor 6 rotates, it directly drives the sliding wheel 4 to rotate.

[0025] In order to enable the working vehicle 2 to move stably and be stably connected when sliding along the length direction of the load-bearing main beam 1, the utility model is provided with a guide mechanism 23.

[0026] The guide mechanism 23 includes two clamping plates 231 arranged opposite to each other and two reinforcement frames 232. The tops of the two clamping plates 231 are integrally connected with two guardrails 22 arranged opposite to each other, and are clamped on the two sides of the load-bearing main beam 1 with long sides. Each reinforcement frame 232 covers and tightens the standing platform 21, the clamping plates 231 and the load-bearing main beam 1. The two clamping plates 231 clamp the load-bearing main beam 1 together to provide guidance for the movement of the work vehicle 2 and prevent the vehicle from tilting during movement. The reinforcement frame 232 keeps the work vehicle 2 in a straight state, preventing the work vehicle 2 from tipping over or even falling down, and reinforcing the stability of the connection of the work vehicle 2.

[0027] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
