[0026] The following will describe in detail the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0027] In the present utility model, unless otherwise stated, the directional terms such as "upper, lower, middle, inside, inner, outer" included in the terms only represent the orientation of the term in the normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation of the term.

[0028] See Figure 1 , the present utility model provides a movable maintenance door for a truss crane. The movable maintenance door for a truss crane includes a pair of opposed doors 1. The outer ends of the two doors 1 are respectively detachably installed on the wall of the workshop through a door hinge assembly 2, and the inner ends are connected through a bolt assembly 3 and are arranged to be able to open one or two doors and close and lock the two doors; wherein,

[0029] One end of the door hinge assembly 2 extending into the wall is provided with a stiffening plate 4. The door 1 includes a door frame column 11. A plurality of horizontal beams 12 are arranged vertically on the inner side of the door frame column 11. Moreover, reinforcing diagonal braces 13 are arranged crosswise on the diagonal of the door frame column 11.

[0030] Through the above technical solution, the present utility model provides a pair of opposed doors 1. The outer ends of the two doors 1 are respectively detachably installed on the wall of the workshop through a door hinge assembly 2, and the inner ends are connected through a bolt assembly 3 and are arranged to be able to open one or two doors and close and lock the two doors. At the same time, in order to enhance the mechanical strength and structural stability, a stiffening plate is provided at one end of the door hinge assembly extending into the wall. Moreover, a plurality of horizontal beams 12 are arranged vertically on the inner side of the door frame column 11, and reinforcing diagonal braces 13 are also arranged crosswise on the diagonal of the door frame column 11. In this way, by using a movable maintenance door to connect with the workshop, it can be used as the wall of a steel structure workshop in daily use and can be opened when in use. It is not only simple in construction, safe in structure, economical and practical, and can be applied to most workshops equipped with truss cranes, but also avoids demolishing the steel structure wall during maintenance, thereby saving the use cost of the workshop and solving the problem of difficult maintenance of workshops equipped with truss cranes.

[0031] In the actual use process, due to the relatively large overall area of the wall of the workshop, the area of the corresponding movable maintenance door for a truss crane will also be relatively large. If only a bolt assembly 3 is installed at a certain part of the door 1 for door locking, the effect will be poor. Once it encounters an external force, it is easy to shake, or even twist due to uneven force. In order to avoid the occurrence of the above situation, preferably, at least two groups of bolt assemblies 3 are provided and are respectively arranged in the upper half and the lower half of the door 1, so that the door 1 can be locked and restricted from two positions up and down, making the closed movable maintenance door for a truss crane more stable.

[0032] In this embodiment, in order to facilitate the operator to manually apply force to open the overhead crane movable maintenance door according to the usage requirements, preferably, a pair of symmetric handles 5 are provided at the middle parts inside the two door leaves 1.

[0033] Furthermore, in order to prevent the above-mentioned handle 5 from rusting and becoming easily damaged after long-term use, and unable to achieve a long service life, preferably, the handle 5 is made of stainless steel. Using a stainless steel handle is not only convenient for operation and has a beautiful appearance, but also is not easy to rust and has a long service life, greatly reducing the maintenance cost.

[0034] When using the overhead crane movable maintenance door, in order to ensure the consistency of the factory building wall surface and optimize the operation environment inside the factory building, preferably, a steel plate layer 6 is wrapped on the outer vertical surface of the door leaf 1. In this way, this steel plate layer 6 can be regarded as a wall surface for use, which is safe and reliable.

[0035] In addition, when the overhead crane needs to enter and exit the factory building for debugging frequently and for a long time, repeatedly opening and closing the overhead crane movable maintenance door is time-consuming and laborious, lengthening the maintenance cycle and seriously affecting the maintenance work efficiency. In order to solve this technical problem, in another embodiment, as Figure 2 shown, preferably, a notch is formed at the upper half of the door leaf 1 near the overhead crane, so that when the two door leaves 1 are closed, the two notches cooperate to form a gap for the overhead crane to pass through. After adopting this form, when the overhead crane is unloaded, it is not necessary to open the entire overhead crane movable maintenance door (see Figure 3 ), and only need to drive the overhead crane to move out of the factory building through the gap formed on the overhead crane movable maintenance door, and then the maintenance can be carried out immediately, which speeds up the maintenance speed and is energy-efficient.

[0036] In addition, in order to further improve the strength and stability of the overhead crane movable maintenance door, preferably, the door frame columns 11, the horizontal beams 12 and the strengthening diagonal braces 13 are made of angle steel.

[0037] At the same time, in order to extend the service life of the bolt assembly 3, preferably, the bolt assembly 3 is a zinc alloy bolt assembly.

[0038] To sum up, the overhead crane movable maintenance door provided by the present utility model effectively solves the maintenance problem of the overhead crane, that is, it avoids the trouble in using the overhead crane during maintenance and the waste of wall demolition, responds to the environmental protection requirements, optimizes the economic cost, and increases the production efficiency. At the same time, it can also improve the work efficiency of the operator, ensure the life and health safety of the operation technicians, and reduce the labor cost and maintenance cost.

However, the present utility model is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present utility model, various simple modifications can be made to the technical solution of the present utility model, and these simple modifications all fall within the protection scope of the present utility model.

[0040] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present utility model will not separately describe various possible combination methods.

[0041] Furthermore, any combination can be made among various different embodiments of the present utility model, as long as it does not violate the idea of the present utility model, and it should also be regarded as the content disclosed by the present utility model.
