Description

Technical Field

[0001] This utility model relates to the field of protective shed technology, and more specifically, to a movable crossbeam for a telescopic protective shed. Background Technology

[0002] Telescopic protective canopies are commonly used on equipment such as machine tools and machining centers. Located on top of the equipment, they protect the components on the equipment and prevent the external environment from affecting its operation.

[0003] Currently, telescopic protective sheds are controlled by a drive device to move a moving crossbeam. The moving crossbeam has rollers, which slide to unfold the shed fabric. However, most existing moving crossbeams have large rollers that not only take up space but also have poor stability and are prone to swaying during movement. Therefore, this utility model proposes a moving crossbeam for telescopic protective sheds. Utility Model Content

[0004] 1. Technical problems to be solved In view of the problems existing in the prior art, the purpose of this utility model is to provide a movable crossbeam for a telescopic protective shed, which aims to solve the problem that the rollers installed on the movable crossbeams in the prior art are usually large in size, which not only takes up space, but also has poor stability and is easy to shake during movement.

[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution: A movable crossbeam for a telescopic protective shed includes a profile movable beam. The two symmetrical ends of the profile movable beam are detachably connected to sliding shells. Limiting components are fixedly connected inside each of the two sliding shells. A set of parallel rollers is rotatably connected inside each of the two limiting components. The number of parallel rollers in each set is set to one or more, arranged in parallel and equidistant.

[0006] A movable crossbeam for a telescopic protective shed includes a profile movable beam. The two symmetrical ends of the profile movable beam are respectively detachably connected to sliding shells. Limiting components are fixedly connected inside each of the two sliding shells. A set of cross rollers is rotatably connected inside each of the two limiting components. The number of cross rollers in each set is set to one or more, arranged in an alternating plug-in manner.

[0007] As a preferred embodiment of this utility model, the profile moving beam is fixedly connected with multiple fixed inner tubes, and both sliding shells are provided with side connection hole groups, and the two side connection hole groups correspond to the symmetrical ends of the multiple fixed inner tubes respectively.

[0008] As a preferred embodiment of this utility model, each pair of adjacent fixed inner tubes is fixedly connected with a reinforcing rib.

[0011] As a preferred embodiment of this utility model, the top ends of the two sliding shells are fixedly connected to two parallel rollers or two intersecting rollers respectively.

[0012] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: (1) In this scheme, a sliding shell is connected to each end of the profile moving beam. Limiting components are provided in both sliding shells. The two limiting components can restrict the sliding shells so that the two sliding shells can move in a straight line on the main beam stably, avoiding shaking when the profile moving beam drives the protective canopy to extend and retract. A set of parallel rollers or cross rollers are rotatably connected in each of the two limiting components. The number of parallel rollers or cross rollers in each set is at least two. The multiple parallel rollers in each set are arranged in parallel, and the multiple cross rollers in each set are arranged in an alternating manner, which can make the two sliding shells slide smoothly on the main beam. Moreover, the volume of each set of parallel rollers or cross rollers is small, which can effectively save space. Attached Figure Description

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" 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 an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Example 1: Please see Figure 1-4 A movable crossbeam for a telescopic protective shed includes a profile movable beam 1. Sliding shells 2 are detachably connected to the symmetrical ends of the profile movable beam 1. Limiting components 3 are fixedly connected inside each of the two sliding shells 2. A set of parallel rollers 4a is rotatably connected inside each of the two limiting components 3. The number of parallel rollers 4a in each set is set to one or more and arranged in parallel at equal intervals.

[0019] In this embodiment, the profile moving beam 1 is used to connect the canopy of the telescopic protective shed. It slides on the main beam through the sliding shells 2 connected at both ends, thereby driving the canopy to telescopically protect the equipment. Limiting components 3 are respectively provided in the two sliding shells 2. The two limiting components 3 can limit the lateral swaying of the two sliding shells 2 on the main beam, ensuring the stability of the profile moving beam 1 when it moves. Each of the two limiting components 3 is provided with one or more sets of parallel rollers 4a. The two sets of parallel rollers 4a can keep the sliding of the two sliding shells 2 smooth. In addition, the two sets of parallel rollers 4a are small in size and save space.

[0020] Example 2: Please see Figure 1-4 A movable crossbeam for a telescopic protective shed includes a profile movable beam 1. Sliding shells 2 are detachably connected to the symmetrical ends of the profile movable beam 1. Limiting components 3 are fixedly connected inside each of the two sliding shells 2. A set of cross rollers 4b is rotatably connected inside each of the two limiting components 3. The number of cross rollers 4b in each set is set to more than one and arranged in an alternating plug-in manner.

[0021] In this embodiment, the profile moving beam 1 slides on the main beam through two sliding shells 2, thereby driving the protective canopy to extend and retract. Each set of cross rollers 4b inside the two sliding shells 2 has at least two rollers and they are arranged in an alternating pattern. This saves space while ensuring the stability of the two sliding shells 2 sliding on the main beam.

[0022] In any of the above embodiments, it should be noted that: Please see Figure 1-4 The profile moving beam 1 is fixedly connected with multiple fixed inner tubes 11. Both sliding shells 2 are provided with side connection hole groups 21, and the two side connection hole groups 21 correspond to the symmetrical ends of the multiple fixed inner tubes 11 respectively.

[0023] Among them, multiple fixed inner tubes 11 correspond to two side connecting hole groups 21, and with the help of bolts, positioning pins and other accessories, the two sliding shells 2 can be fixed, so that the two sliding shells 2 are stable at both ends of the profile moving beam 1.

[0024] Please see Figure 2 Each pair of adjacent fixed inner tubes 11 is fixedly connected with a reinforcing rib 5.

[0025] Among them, multiple reinforcing ribs 5 are fixedly connected between multiple fixed inner tubes 11, which can not only improve the strength of multiple fixed inner tubes 11, but also improve the overall strength of the profile moving beam 1.

[0026] Please see Figure 1-2 The top of the profile moving beam 1 is provided with an installation groove 12, and the top of the two sliding shells 2 are provided with upper connecting hole groups 22, and the two upper connecting hole groups 22 correspond to the installation groove 12.

[0027] Among them, fastening accessories such as pins and bolts can be placed in the mounting groove 12 in a concealed manner. The two sliding shells 2 are fixed by passing through the two upper connecting hole groups 22, which can further improve the stability of the two sliding shells 2 at both ends of the profile moving beam 1.

[0028] Please see Figure 3-4 The inner sides of both limiting components 3 are provided with grooves 31.

[0029] Among them, the two limiting components 3 restrict the two sliding shells 2 by contacting the side ends of the main beam, so as to prevent the two sliding shells 2 from shaking during the sliding process. The two limiting components 3 can reduce the contact surface with the main beam by opening two grooves 31, thereby reducing the friction generated by the two sliding shells 2 during the sliding process while ensuring the restriction effect of the two sliding shells 2.

[0030] Please see Figure 1-4 The top of each of the two sliding shells 2 is fixedly connected with a 6, and the two 6s respectively penetrate into the sliding shell 2 and correspond to the two parallel rollers 4a or the two cross rollers 4b.

[0031] Among them, the two 6s can respectively inject oil into the inner side of the two sliding shells 2 to achieve lubrication of the two parallel rollers 4a or the two cross rollers 4b, ensuring the movement effect of the profile moving beam 1.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
