Description

Technical Field

[0001] This utility model relates to the field of traction machine guard technology, and in particular to an adjustable traction machine guard. Background Technology

[0002] The elevator traction machine is the power unit of the elevator, also known as the elevator main unit. Its function is to deliver and transmit power to make the elevator run. It consists of an electric motor, brake, coupling, gearbox, traction sheave, frame, guide wheels, and auxiliary handwheel.

[0003] Chinese patent CN205061283U discloses an adjustable traction machine cover, including a first cover, a second cover, a connecting plate, a first connector, and a second connector. The second cover is located on the side of the first cover adjacent to the traction machine where the guide wheel is located. The first cover includes a first panel and a bottom plate, with a first side plate connecting the first panel and the bottom plate. The connecting plate is located at the lower end of the first panel, and the connecting plate and the first panel are connected by the first connector. The second cover includes a second panel and a second side plate perpendicular to the second panel. The second panel and the first panel are parallel, and the top of the second side plate is hinged to the first side plate. A second connector is provided between the second panel and the connecting plate. This utility model has a simple structure and can meet different wrap angle requirements by adjusting the left and right positions of the second cover, thus providing good protection for the traction machine.

[0004] However, due to the presence of the external connecting plate, this technical solution increases the size of the protective cover, makes the structure more complex, and is inconvenient to install. Operators may experience interference and inconvenience when using the traction machine. There is also the possibility that operators may trip over the connecting plate, resulting in insufficient safety. Furthermore, this protective cover only has one adjustable cover, limiting its applicability. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing an adjustable protective cover for traction machines. By installing two auxiliary covers on both sides of the main body of the protective cover, and the positions of the two auxiliary covers are adjustable, the protective cover can flexibly adapt to the installation requirements of various traction machines. There is no need to redesign a fixed-position protective cover for each type of traction machine, which improves versatility and has a wide range of applications.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable protective cover for a traction machine includes: a first cover, a second cover disposed on one side of the first cover, and a third cover disposed on the other side of the first cover, wherein the positions of the second cover and the third cover on the first cover are adjustable.

[0008] Preferably, both the second cover and the third cover are fixedly connected to the side plate of the first cover by a number of fasteners.

[0009] Preferably, both the second cover and the third cover are provided with a plurality of waist-shaped grooves that are adapted to the fasteners.

[0010] Preferably, the waist-shaped groove is arc-shaped.

[0011] Preferably, the second cover and the third cover are slidably connected to the side plate.

[0012] Preferably, both the second cover and the third cover are triangular in shape.

[0013] Preferably, the second cover and the third cover do not interfere with each other.

[0014] Preferably, the external dimensions of the second cover and the third cover are adapted to the external dimensions of the first cover.

[0015] Preferably, the side plate is provided with a plurality of through holes.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) By installing a second cover and a third cover on both sides of the first cover, the position of the second cover and the third cover can be adjusted as needed when maintaining or repairing the traction machine, providing more space and a more convenient angle for the operator, facilitating the inspection, repair or replacement of the internal components of the traction machine, improving work efficiency. The position can also be roughly fixed first according to the actual situation, and then the position of the second cover and the third cover can be finely adjusted according to the actual assembly situation, ensuring that the cover and the traction machine are more closely and reasonably matched, avoiding installation problems or safety hazards caused by position deviation.

[0018] (2) The present invention uses several fasteners to fix the second cover and the third cover to the side plate of the first cover. The fasteners can provide a stable connection force to ensure that the second cover and the third cover will not loosen or fall off due to vibration, impact or other factors during use, thus ensuring the overall structural stability of the cover and providing reliable protection for the traction machine.

[0019] (3) By setting multiple arc-shaped waist grooves in the second and third covers, this utility model provides a clear range of movement for the position adjustment of the second and third covers, making the position adjustment more orderly and controllable. Operators can flexibly move the second and third covers within the length range of the waist grooves as needed to achieve precise positioning, thereby improving installation efficiency. In addition, the arc-shaped waist grooves can disperse stress to a certain extent and avoid stress concentration, thereby enhancing the structural strength of the cover during adjustment and use and improving the durability of the cover.

[0020] (4) By setting the second cover and the third cover to be mutually non-interfering, the operator will not be affected by the other cover when adjusting, disassembling or installing one of the second cover or the third cover. The operator can operate each cover independently, which improves work efficiency, reduces the complexity and error probability in the operation process, and the non-interference between the second cover and the third cover can effectively avoid collision or friction between the two, thereby reducing noise, wear and other problems caused by collision, extending the service life of the cover, and also helping to keep the inside of the cover clean and stable.

[0021] In summary, this utility model has the advantages of strong versatility, wide applicability, good stability and firmness, long service life, simple structure and convenient assembly and disassembly. Attached Figure Description

[0027] Example

[0028] like Figures 1-3 As shown, this embodiment provides an adjustable cover for a traction machine, including: a first cover 1, a second cover 2 disposed on one side of the first cover 1, and a third cover 3 disposed on the other side of the first cover 1. The positions of the second cover 2 and the third cover 3 on the first cover 1 are adjustable, so that the cover can flexibly adapt to the installation requirements of various traction machines, without the need to redesign a fixed-position cover for each traction machine, thus improving versatility and wide applicability.

[0029] During maintenance or repair of the traction machine, the positions of the second cover 2 and the third cover 3 can be adjusted as needed to provide operators with more space and a more convenient angle, making it easier to inspect, repair or replace the internal components of the traction machine and improve work efficiency.

[0030] Meanwhile, when installing the protective cover, the position can be roughly fixed first according to the actual situation, and then the positions of the second cover 2 and the third cover 3 can be finely adjusted according to the actual assembly situation to ensure that the protective cover and the traction machine are more closely and reasonably matched, and to avoid installation problems or safety hazards caused by position deviation.

[0031] In this embodiment, the second cover 2 and the third cover 3 are both fixedly connected to the side plate 11 of the first cover 1 by a number of fasteners 21. The fasteners 21 can provide a stable connection force to ensure that the second cover 2 and the third cover 3 will not loosen or fall off due to vibration, impact or other factors during use, thus ensuring the overall structural stability of the cover and providing reliable protection for the traction machine.

[0032] In this embodiment, the fastener 21 is preferably a bolt structure, which makes the disassembly and installation of the cover more convenient. It is only necessary to loosen or tighten the corresponding bolts, which facilitates the replacement, repair or maintenance of the cover or the traction machine, and improves the convenience of maintenance.

[0033] In this embodiment, both the second cover 2 and the third cover 3 are provided with a plurality of waist-shaped grooves that are adapted to the fastener 21. The waist-shaped grooves provide a clear range of movement for the position adjustment of the second cover 2 and the third cover 3, making the position adjustment more orderly and controllable. Operators can flexibly move the second cover 2 and the third cover 3 within the length range of the waist-shaped grooves as needed to achieve precise positioning and thus improve installation efficiency.

[0034] In this embodiment, the waist-shaped groove is arc-shaped, which makes the adjustment process smoother and reduces possible jamming or interference during the adjustment process. In addition, the arc-shaped waist-shaped groove can disperse stress to a certain extent and avoid stress concentration, thereby enhancing the structural strength of the cover during adjustment and use and improving the durability of the cover.

[0035] In this embodiment, the second cover 2 and the third cover 3 are slidably connected to the side plate 11. Operators can change the position of the cover by simple sliding operations, which greatly improves the efficiency of position adjustment and saves time and effort.

[0036] In this embodiment, both the second cover 2 and the third cover 3 are triangular in shape. The triangular structure has good stability and can withstand forces from different directions, making the second cover 2 and the third cover 3 more stable during use and less prone to deformation or damage. This better protects the internal components of the traction machine from external impacts or collisions. Preferably, the two are completely identical and symmetrically arranged on both sides of the first cover 1. The identical structure makes the second cover 2 easy to mass-produce and has low operating costs.

[0037] In this embodiment, the second cover 2 and the third cover 3 do not interfere with each other. That is, when one of the second cover 2 or the third cover 3 is adjusted, disassembled or installed, it will not be affected by the other cover. The operator can operate each cover independently, which improves work efficiency and reduces the complexity and probability of error in the operation process. Moreover, the fact that the second cover 2 and the third cover 3 do not interfere with each other can effectively avoid collisions or friction between the two, thereby reducing noise, wear and other problems caused by collisions, extending the service life of the cover, and also helping to keep the inside of the cover clean and stable.

[0038] In this embodiment, the top of the second cover 2 and the top of the third cover 3 can be hinged to the first cover 1. The arc-shaped waist groove can use the hinge center as the center of a circle, and the second cover 2 and the third cover 3 can rotate around the hinge center, making the adjustment of the second cover 2 and the third cover 3 more convenient and quick.

[0039] In this embodiment, the outer dimensions of the second cover 2 and the third cover 3 are adapted to the outer dimensions of the first cover 1. The adapted outer dimensions can ensure that the connection between the various parts of the cover has good sealing performance, effectively preventing dust, debris and other objects from entering the traction machine. At the same time, it can also block external moisture, oil and other substances from corroding the traction machine, improve the protection level of the traction machine, and ensure its normal operation.

[0040] Of course, the side plate 11 is provided with a number of through holes 12, which are used for heat dissipation of the traction machine to avoid problems such as scrapping due to excessive temperature.

[0041] In addition, the second cover 2 and the third cover 3 can have the same structure, or different structures can be selected according to actual needs to adapt to different working conditions of the traction machine.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
