Description

Technical Field

[0001] The utility model belongs to the technical field of the lifting of rolling doors in battery swapping stations, and particularly relates to a manual lifting device for a rolling door in a battery swapping station when power is cut off. Background Technique

[0002] With the vigorous development of new energy vehicles, the acceptance and demand of the public for new energy vehicles are increasing day by day. A rolling door is a door in which multiple articulated door panels are connected in series and rotate up and down around a scroll above the door in a fixed slideway. The rolling door plays the same role as a wall in horizontal partitioning. It consists of multiple parts such as curtain boards, seat boards, guide rails, supports, scrolls, boxes, control boxes, rolling door machines, limiters, door lintels, button switches, and safety devices. Rolling doors need to be installed at the entrances and exits of new energy vehicle battery swapping stations to partition the entrances and exits.

[0003] However, most of the automatic rolling doors on the market at present are controlled by electricity for lifting. When a power outage occurs, there will be a problem of being unable to use, and the practicability is relatively low. Content of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide a manual lifting device for a rolling door in a battery swapping station when power is cut off, which can manually open and close the rolling door in case of accidental power cut.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: a manual lifting device for a rolling door in a battery swapping station when power is cut off, the device includes:

[0006] An installation bracket, a transmission mechanism, a driving mechanism, a steel rope bracket, and a manual pulling mechanism. The installation bracket is arranged on one side of the rolling door. The driving mechanism is arranged on one side of the installation bracket, and the driving mechanism is sleeved on the outer periphery of one end of the transmission mechanism. The steel rope bracket is arranged on one side of the driving mechanism, and the manual pulling mechanism passes through the steel rope bracket and is connected to one end of the transmission mechanism;

[0007] An elastic mechanism is further sleeved on the outer periphery of the transmission mechanism, and the elastic mechanism is used to reset the rotating shaft.

[0008] Preferably, the transmission mechanism includes a transmission shaft, an adapter, and a connecting ring. The adapter and the connecting ring are respectively arranged at both ends of the transmission shaft. A hexagonal countersunk hole is arranged at one end of the adapter away from the transmission shaft, and a clamping groove is arranged on the outer periphery of the transmission shaft along its length direction.

[0009] Preferably, the driving mechanism includes a mounting box, a driving gear and a link buckle. The mounting box is arranged on one side of the mounting bracket. The mounting box is provided with a mounting hole. One end of the transmission shaft is placed in the mounting hole. The driving gear is sleeved on this end of the transmission shaft. The link buckle is matched with the driving gear.

[0010] Preferably, the elastic mechanism includes a retaining piece and a spring. The retaining piece is sleeved on one end of the transmission shaft. The spring is sleeved on the outer periphery of the transmission shaft, and the spring is arranged between the retaining piece and the mounting box.

[0011] Preferably, the manual pulling mechanism includes a steel cable, a connecting disc, a handle and a toothed disc. One end of the steel cable is connected to the connecting ring, and the other end of the steel cable is connected to the connecting disc. The handle is arranged on one side of the connecting disc. The connecting disc is rotatably connected to the toothed disc through a central pin.

[0012] Preferably, the mounting bracket is set as a "door"-shaped mounting bracket.

[0013] The beneficial effects of the present utility model are as follows:

[0014] When the rolling shutter door is in normal operation, the handle is pressed down to pull out the transmission shaft through the steel cable, so that the transmission shaft is not connected to the rolling shutter door motor shaft. At this time, the spring is in a compressed state;

[0015] When the rolling shutter door encounters a fault and loses power, the handle is manually released. The transmission shaft is reset by the spring, so that the connecting piece with a hexagonal countersunk head hole on the transmission shaft engages with the rolling shutter door motor shaft, thereby realizing that the rolling shutter door can be lifted and lowered by manually pulling the link buckle, solving the problem that the rolling shutter door cannot be used in the case of power failure and improving its practicability.

The hand-pulling mechanism 500 passes through the steel rope bracket 400 and is connected to one end of the transmission mechanism 200;

[0031] An elastic mechanism 600 is further sleeved on the outer periphery of the transmission mechanism 200. The elastic mechanism 600 is used to reset the rotating shaft.

[0032] Further, refer to Figure 2 As shown, the transmission mechanism 200 includes a transmission shaft 201, an adapter 202 and a connecting ring 203. The adapter 202 and the connecting ring 203 are respectively arranged at both ends of the transmission shaft 201. A hexagon countersunk hole is arranged at one end of the connecting member away from the transmission shaft 201. A clamping groove 204 is arranged on the outer periphery of the transmission shaft 201 along its length direction. The clamping groove 204 is used to match with the convex ribs arranged on the connecting member to realize the clamping connection between the connecting member and the transmission shaft 201. The transmission shaft 201 and the connecting member can rotate synchronously.

[0033] In addition, the drive mechanism 300 includes an installation box 301, a drive gear 302, and a link buckle 303. The installation box 301 is arranged on one side of the installation bracket 100.

The transmission mechanism 200 is axially installed into the drive mechanism 300, and the transmission shaft 201 is manually pushed to check whether the action of the spring 602 pushing out the transmission shaft 201 is smooth without jamming. Then, the steel cable 501 is inserted into the connecting ring 203, and the handle 503 is used to operate to check whether the telescopic movement of the transmission shaft 201 is smooth without jamming. Finally, the hexagonal countersunk hole of the connecting piece arranged at the end of the transmission shaft 201 is engaged with the hexagonal shaft on the rolling shutter door.

[0040] When the rolling shutter encounters accidental power failure, the manual release handle 503 can be used to engage the hexagonal counterbore of the connecting piece provided at the end of the transmission shaft 201 with the hexagonal shaft on the rolling shutter through the reset of the spring 602, and the link buckle 303 is pulled clockwise or counterclockwise to drive the rolling shutter to open and close.

[0041] Under the normal operation state of the rolling shutter, the transmission shaft 201 is tightened by the hand-pulled steel rope 501 and the handle 503, the spring 602 on the elastic mechanism 600 is in a compressed state, and the connecting piece of the transmission shaft 201 is not connected to the rolling shutter motor shaft.
