Description

Technical Field

[0001] The utility model relates to the field of cable cars, in particular to a non-rebound alarm device for a draw-out device used in a separate cable car system. Background Art

[0002] Our company has developed a split cable car system that separates the car and the holding arm in the waiting area, making it convenient for passengers to get on and off the car. We submitted a patent application on August 2, 2024, with application number 202411055161.0.

[0003] In actual operation, although our split cable car system is well designed, it may still encounter some occasional accidents. In particular, when the telescopic block does not rebound normally due to various reasons (such as foreign objects stuck, mechanical wear, material deformation under extreme weather conditions, etc.), the detached base cannot be locked normally when it is reattached, causing the risk of the cable car falling. Therefore, an alarm device is urgently needed to remind the operator to make an emergency stop and repair in time when the pull rod of the telescopic block does not rebound normally, so as to avoid accidents. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, the invention solves the problem that when the telescopic stopper is stuck due to various reasons, a hard collision occurs between the pull rod and the extraction device, causing damage.

[0005] The utility model provides a non-rebound alarm device for a pull-out device of a separate cable car system. The alarm device is fixedly arranged on the side where the pull rod of the pull-out device is driven out, and comprises a trigger device, a guide rail and a pressure-sensitive alarm device;

[0006] The trigger device is slidably arranged on the guide rail, and a guide surface is provided on the side of the trigger device close to the extraction device to convert the lateral displacement of the pull rod into the longitudinal displacement of the trigger device, so that the trigger device is squeezed by the unrebounded pull rod and moves toward the pressure-sensitive alarm device.

[0007] Furthermore, the extraction device and the alarm device are fixedly arranged side by side on a fixed plate, and the position of the guide surface close to one end of the extraction device is in the same straight line as the inner edge of the horizontal bending section of the extraction device.

[0008] Furthermore, the guide rail is fixedly arranged perpendicular to the fixed plate, a slide rail is arranged on the upper surface of the guide rail, and a slideway is arranged on the lower surface of the trigger device to cooperate with the slide rail.

[0009] Furthermore, the pressure-sensing alarm device is arranged on a fixed plate, and the trigger device is fixedly provided with a trigger rod at a position corresponding to the pressure-sensing alarm device.

[0010] Furthermore, a return spring is arranged between the trigger device and the fixing plate, and the return spring is sleeved on the outside of the trigger rod.

[0011] As a preferred solution, the trigger device is a U-shaped groove, and triangular protrusions are arranged at both ends of the U-shaped groove to form a guide surface.

[0012] As a preferred solution, the included angle between the guide surface and the guide rail is 30 degrees to 60 degrees.

[0013] As a preferred solution, the guide rail is provided with an oblique support fixedly connected to a fixed plate.

[0014] As a preferred solution, the pressure sensing alarm device is electrically connected to a control center and sends an alarm to the control center when the pressure sense exceeds a set threshold.

[0015] The beneficial effects of the utility model are:

[0016] The utility model is provided with a trigger device. When the unretracted alarm trigger device squeezes the guide surface because the rod head is not retracted normally, the trigger device generates relative movement, the spring is compressed, and when it reaches the designed pressure-sensitive alarm device contact surface, the alarm circuit is connected to generate an audible and visual alarm to alert the staff. When the rod head passes the unretracted alarm trigger device, the trigger device returns to its original position under the action of the spring, and the alarm circuit is disconnected accordingly, and continues to detect whether the rod head of the next car is retracted normally.

[0024] To illustrate the features of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0025] Embodiment 1:

[0026] See also Figures 1 to 3 The present embodiment provides a non-rebound alarm device for a pull-out device of a separate cable car system, including an alarm device fixedly arranged on the side where the pull rod 2 of the pull-out device 1 is extended, including a trigger device 3, a guide rail 4 and a pressure-sensitive alarm device 5; the trigger device 3 is slidably arranged on the guide rail 4, and the trigger device 3 is provided with a guide surface 31 close to the pull-out device 1 to convert the lateral displacement of the pull rod 2 into the longitudinal displacement of the trigger device 3, so that the trigger device 3 is squeezed by the non-rebound pull rod 2 to move toward the pressure-sensitive alarm device 5, and the pressure-sensitive alarm device 5 is electrically connected to the control center, and an alarm is sent to the control center when the pressure exceeds the set threshold.

[0027] In this embodiment, the extraction device 1 and the alarm device are fixedly arranged side by side on the fixed plate 6, and the position of the guide surface 31 close to one end of the extraction device 1 is in the same straight line as the inner edge of the horizontal bending section of the extraction device 1. The guide rail 4 is fixedly arranged perpendicular to the fixed plate 6, and a slide rail 41 is arranged on the upper surface of the guide rail 4, and a slideway is arranged on the lower surface of the trigger device 3 to cooperate with the slide rail 41. The pressure-sensitive alarm device 5 is arranged on the fixed plate 6, and a trigger rod 32 is fixedly arranged on the trigger device 3 corresponding to the position of the pressure-sensitive alarm device. When the non-rebound alarm trigger device squeezes the guide surface 3 because the pull rod 2 is not retracted normally, the trigger device slides along the guide rail toward the fixed plate 6. When it reaches the designed contact surface of the pressure-sensitive alarm device 5, the alarm circuit will be connected to generate an audible and visual alarm to alert the staff.

[0028] In this embodiment, a return spring 7 is further provided between the trigger device 3 and the fixed plate 6. The return spring 7 is sleeved on the outside of the trigger rod 32. When the pull rod 2 passes over the unretracted alarm trigger device, the trigger device 3 returns to its original position under the action of the return spring 7, and the alarm circuit is disconnected accordingly, and continues to detect whether the pull rod 2 of the next car is retracted normally.

[0029] The trigger device 3 is a U-shaped groove, and triangular protrusions 33 are arranged at both ends of the U-shaped groove to form a guide surface 31. The trigger device 3 is specially designed in this embodiment. The unretracted alarm trigger device is the same as the extraction guide plate. In order to avoid uneven force to generate unnecessary force or torque, the U-shaped groove is set to have upper and lower layers to adapt to the upper and lower working surfaces of the pull rod head.

[0030] The guide surface 31 must be an inclined surface with a certain angle to meet the requirement that the position of the pull rod 2 may exist within a certain range and does not prevent the pull rod 2 from continuing to move forward at the original speed. Therefore, in this embodiment, the angle between the guide surface 31 and the guide rail 4 is 30 degrees.

[0031] In addition, this embodiment also makes an adaptability improvement to the guide rail 4 , and an oblique support 42 is provided on the guide rail 4 to fix the fixing plate 6 , so as to enhance the supporting force of the guide rail 4 on the trigger device 3 .

[0032] Embodiment 2:

[0033] See also Figure 4 In this embodiment, the triangular protrusions 33 at both ends of the trigger device 3 in embodiment 1 are improved into trapezoidal protrusions. This setting can extend the reminder time of the alarm and give the operator sufficient reaction time. However, compared with embodiment 1, the force is not balanced enough. Therefore, for heavy-weight carriages, the stability is not enough. Designers can choose between the two schemes according to actual conditions.

[0034] The above embodiments and drawings are only used to illustrate the technical solution of the utility model, and are not intended to limit the utility model. The utility model is described in detail with reference to the preferred embodiments. It should be understood by ordinary technicians in this field that the changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the utility model do not deviate from the purpose of the utility model and should also fall within the scope of protection of the claims of the utility model. Other related technical structures not fully disclosed in the utility model are prior art in the field.
