Description

Technical Field

[0001] The present application relates to the technical field of mobile manned equipment and mobile hoisting-assisted production and maintenance, and in particular to a manned trackless mobile gantry. Background Art

[0002] With the continuous development and upgrading of manufacturing, the installation, assembly, repair and maintenance of large equipment, pit equipment, aircraft and trains require safe and convenient auxiliary manned equipment; the auxiliary production of large and long wind blade mold fabric laying requires special equipment. Whether a simpler, cost-effective and safe solution can be used is the actual demand of specific industries.

[0003] In assembly and maintenance, some assembly parts and materials need to be hoisted. Obviously, the simple need to carry people cannot better meet the functional requirements of the use scenario. Therefore, a mechanism for hoisting is added in this case. While meeting the needs of manned climbing or diving, it can also hoist materials, making the equipment more practical.

[0004] The solution usually adopted to solve this kind of application is to use aerial platforms to carry people; use cranes or overhead cranes to lift materials or assembly parts. Even if there is enough space, such large equipment requires long-term use, whether it is early installation or later replacement of parts, maintenance and repair. Obviously, from a long-term cost perspective, each rental of aerial platforms and lifting vehicles will increase costs.

[0005] However, in many scenarios, the space occupied by the crane is too large, and such conditions are not available on site. If a factory crane is used for lifting, if there are many lines, each line needs to be equipped with a crane, which will greatly increase the cost. In this case, the movable multifunctional gantry can be moved to other scenes as needed. Utility Model Content

[0006] In order to make up for the above shortcomings, the present application provides a manned trackless mobile gantry, which aims to improve the assembly, maintenance and other occasions that generally require the lifting of some assembly parts, materials, etc. Obviously, the simple manned demand cannot better solve the functional requirements of the use scenario, and a crane or an overhead crane is used to lift materials or assembly parts; even if there is enough space, this kind of large equipment is a long-term use case whether it is early installation or later replacement of parts, maintenance and repair, etc. Obviously, from the perspective of long-term cost, each rental of a climbing vehicle and a lifting vehicle will increase the cost; but in many scenarios, the space occupied by the crane is too large, and such conditions are not available on site. If a factory overhead crane is used for lifting, if there are many lines, an overhead crane is installed on each line, which will greatly increase the cost.

[0010] In one embodiment of the present application, the manned lifting mechanism comprises a telescopic scissor fork, an electric hoist, a chain and a manned cage, and the mobile trolley is fixed on the lower surface of the upper frame of the telescopic scissor fork;

[0011] The upper end of the electric hoist is rotatably arranged on the upper frame of the gantry, one end of the chain is sleeved on the telescopic scissors fork, the other end of the chain is sleeved on the hook of the electric hoist, and the manned cage is fixed on the lower surface of the lower frame of the telescopic scissors fork.

[0012] In one embodiment of the present application, it also includes an operating table, which is fixed on the manned cage and is electrically connected to the moving trolley, the electric hoist, the hoisting hoist trolley and the walking steering wheel.

[0013] In one embodiment of the present application, a warning projection light is further included, and the warning projection light is fixedly mounted on the gantry.

[0016] In one embodiment of the present application, a road cleaner is further included, and the road cleaner is fixed to the end of the gantry.

[0017] The beneficial effects of this application are:

[0018] 1. It is more suitable for long-line work. The manned cage covers downward from the air, covering a larger area. Its operating dimensions are difficult for ordinary aerial platforms to achieve for equipment with a wide frame and a large upper surface, and it can easily and safely carry a larger load. The safety, cost and size of ordinary aerial platforms will be doubled with each additional weight.

[0019] 2. Regarding the requirements for operating space, ordinary aerial platforms require larger walking passages, while in this case, only two narrower operating passages are required.

[0029] The travel steering wheel 190 and the self-locking universal wheel 192 are both installed on the lower end surface of the gantry 110, and the manned lifting mechanism 150 is installed on the mobile trolley 140. The manned lifting mechanism 150 includes a telescopic scissor fork 151, an electric hoist 152, a chain 153 and a manned cage 154. The mobile trolley 140 is fixed on the lower surface of the upper frame of the telescopic scissor fork 151;

[0030] The upper end of the electric hoist 152 is rotatably arranged on the upper frame of the gantry 110, one end of the chain 153 is sleeved on the telescopic scissor fork 151, and the other end of the chain 153 is sleeved on the hook of the electric hoist 152. The manned cage 154 is fixed on the lower surface of the lower frame of the telescopic scissor fork 151, and also includes an operating table 155, which is fixed on the manned cage 154. The operating table 155 is electrically connected with the mobile trolley 140, the electric hoist 152, the hoisting hoist trolley 160 and the walking steering wheel 190 at the same time. The walking steering wheel 190 and the self-locking universal wheel 192 can realize the overall free movement of the gantry 110 such as forward movement, backward movement, turning at any angle, and U-turning;

[0032] Specifically, the working principle of the manned trackless mobile gantry is as follows: when in use, the manned cage 154 can be moved up and down manually by remote control or operating the operating table 155. At the same time, the setting of the telescopic scissor fork 151 can reduce the swing during movement, which is safer, and can control the work of the hoisting hoist trolley 160 and the walking steering wheel 190. Two hoisting hoist trolleys 160 can be hoisted by one hoist alone, which is more suitable for the scene of two hoists lifting long materials and irregular materials, and two hoisting hoist trolleys 160 are configured, one for The first track 120 and the second track 130 are set so that the mobile trolley 140 and the hoisting hoist trolley 160 can cross-operate. The manned trackless mobile gantry is more suitable for long-line work. The manned cage 154 covers from the air downward, with a larger coverage area. For equipment with a wide frame and a large upper plane, its operating dimensions are difficult to achieve with ordinary aerial vehicles, and in this case, it can It is easier and safer to carry a larger load, while the safety, cost and size of ordinary aerial platforms will be doubled with each additional weight. As for the requirements for operating space, ordinary aerial platforms require larger walking passages, while in this case, only two narrower operating passages are needed. For equipment installed in the pit, ordinary manned aerial platforms cannot complete it, but in this case, it can be safely covered downward. The hoisting hoist trolley 160 for lifting is given the scene requirements of not only manning people, but also can be used for lifting, so that the equipment can make full use of the advantages of the mechanism, and the applicable scenes and functions are more abundant. People standing on the manned cage 154 can control the multi-dimensional operation of the device, and install, lay, repair and other related work on the equipment. It is safe and efficient, and it has a strong lifting function.
