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 trackless mobile gantry with a foreign matter cleaning mechanism. 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 cranes 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, installing an overhead crane on each line will greatly increase the cost. The movable multifunctional gantry in this case can be moved to other scenes as needed. In addition, the current trackless free-walking gantry is often blocked by foreign objects on the road during movement, which hinders the movement of the gantry. If the gantry is forced to pass, it will tilt, reducing the safety of the gantry's movement. Manual cleaning of foreign objects will increase the workload of manual labor and waste manpower, giving users a bad user experience. Utility Model Content

[0026] Example

[0027] See also Figure 1 - Figure 5 , the present application provides a technical solution: a trackless mobile gantry with a foreign matter cleaning mechanism, comprising a gantry 110, a connecting plate 170, a connecting frame 180, an iron brush 190, a running steering wheel 191 and a self-locking universal wheel 192, the running steering wheel 191 and the self-locking universal wheel 192 are both mounted on the lower end surface of the gantry 110, and the connecting plate 170 is fixed to the lower end of the gantry 110;

[0028] The connecting frame 180 is fixed on the connecting plate 170, and the iron brush 190 is inserted on the connecting frame 180. The angle between the iron brush 190 and the connecting plate 170 is less than or equal to 70 degrees. The end of the connecting frame 180 is provided with an arc end face. The setting of the iron brush 190 is used to remove foreign objects from the moving route of the gantry 110. The outer end face of the connecting frame 180 is inclined. The iron brush 190 is installed in the connecting frame 180, and a part of the iron brush 190 is exposed outside the connecting frame 180. A square hole is opened on the iron brush 190, and the mounting hole on the connecting frame 180 is set corresponding to the square hole. It also includes a moving trolley 140, a manned lifting mechanism 150, and a hoisting hoist trolley 160;

[0029] The moving trolley 140 and the hoisting hoist trolley 160 are both installed on the upper end surface of the gantry 110, and the manned lifting mechanism 150 is installed on the moving trolley 140. The setting of the manned lifting mechanism 150 can control the lifting of the manned cage 154, and also includes a first track 120 and a second track 130. The moving trolley 140 is installed on the first track 120, and the hoisting hoist trolley 160 is installed on the second track 130. The first track 120 and the second track 130 are parallel to each other. The manned lifting mechanism 150 includes a telescopic scissor fork 151, an electric hoist 152, a chain 153 and a manned cage 154. The moving 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 set on the upper frame of the gantry 110, one end of the chain 153 is sleeved on the telescopic scissors 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 scissors fork 151, and also includes an operating table 155, which is fixed on the manned cage 154. The operating table 155 is electrically connected to the mobile trolley 140, the electric hoist 152, the lifting hoist trolley 160 and the walking steering wheel 191.

[0031] Specifically, the working principle of the trackless mobile gantry with a foreign body cleaning mechanism 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 operation of the hoisting hoist trolley 160 and the walking steering wheel 191. 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. Two hoisting hoist trolleys 160 are configured, one of which can be a hoist. The other is redundant for safety, ensuring safer hoisting. The travel steering wheel 191 can realize overall free movement such as forward, backward, turning, and U-turn. The setting of the first track 120 and the second track 130 allows the mobile trolley 140 and the hoisting hoist trolley 160 to run crosswise. The inclined connecting frame 180 and the iron brush 190 sweep the foreign objects on the moving path of the gantry 110 to one side. The manned auxiliary assembly gantry structure is more suitable for long-line work. The manned cage 154 covers downward from the air, covering a larger area, and its work is for equipment with a wide frame and a large upper plane. The business dimension is difficult for ordinary aerial platforms to achieve, and in this case, it can easily and safely have 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 channels, while in this case, only two narrower operating channels are required. For equipment installed in the pit, ordinary manned aerial platforms cannot complete it, but in this case, it can be safely covered downwards, and the hoisting hoist trolley 160 is given the scene requirements in addition to manned, and it can also be used for hoisting, allowing the equipment to be installed in the pit. The advantages of the mechanism are fully utilized, and the applicable scenarios and functions are more abundant. A person standing on the manned cage 154 can control the multi-dimensional operation of the device, and perform related work such as installation, laying, and maintenance of the equipment. It is safe and efficient, and has a strong lifting function. In addition, by setting an inclined connecting frame 180 and an iron brush 190, foreign objects on the moving path of the gantry 110 are swept aside, effectively preventing the walking steering wheel 191 and the self-locking universal wheel 192 from pressing on foreign objects, ensuring the normal movement of the gantry 110, saving manpower, and bringing users a better use experience.

[0032] It should be noted that the specific models and specifications of the mobile trolley 140, electric hoist 152, operating table 155, lifting hoist trolley 160 and walking steering wheel 191 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The power supply and principle of the mobile trolley 140, the electric hoist 152, the operating table 155, the hoisting hoist trolley 160 and the traveling steering wheel 191 are clear to those skilled in the art and will not be described in detail here.
