Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to an emergency stop mechanism and a device for trolleys running off-course and impacting cables. Background Art

[0002] Due to the combined influence of various factors such as heavy production tasks, continuous expansion of the work site and the increase in the number of new drivers, tire cranes frequently run off the track when operating the truck.

[0003] In the case of tire deviation, the driver fails to take corrective measures in time or takes corrective measures too late, causing the tire crane to deviate from the predetermined driving route. Especially when the tire crane is close to the cable mounting device, since the device is close to the driving lane, once the truck deviates too much, it is very easy for the truck tire frame to collide with the cable mounting device. This collision will not only cause damage to the cable mounting device and the truck tire frame, but may even cause damage to the cable and tire, thereby causing a safety accident and bringing serious adverse effects.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an emergency stop mechanism and a cable mounting device for a trolley running off the track are proposed. Utility Model Content

[0005] The utility model aims to provide an emergency stop mechanism and a device for preventing a trolley from running off course and hitting a cable, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an emergency stop mechanism, including an emergency stop component, the emergency stop component including an extension frame, a switch housing, a drive rod, a mounting pin, a fastening pin and anti-collision whiskers, the switch housing is fixed by screws at the end of the extension frame, and the drive rod is rotatably mounted at the input end of the switch housing, the end of the drive rod is connected to the mounting pin, and the root of the mounting pin is fixed to the drive rod by a fastening pin, and the mounting pin has anti-collision whiskers extending outward.

[0007] Furthermore, the extension length of the extension frame is 500 mm, and the end of the extension frame is inclined at an angle of 45 degrees.

[0008] Furthermore, the length of the anti-collision whisker is set to 350 mm, and when the anti-collision whisker touches the cable and runs to 90 degrees, the root mounting pin drives the driving rod on the head of the switch housing to rotate, thereby changing the switch state.

[0009] A device for preventing a trolley from running off the track and hitting a cable is provided, wherein the device is provided with an emergency stop mechanism as described above and comprises a trolley guard frame, wherein the front side of the trolley guard frame is fixed to an extension frame by welding, and the trolley guard frame is fixed to the front end of a platform.

[0010] Furthermore, brackets are fixed on both sides of the rear end of the platform, and the brackets are fixed to the back of the vehicle guard frame through reinforcing rods.

[0011] Furthermore, tires are rotatably mounted inside the brackets on both sides, and the tires run on the truck runway.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the utility model is in use, the anti-collision stop limit device for the trolley is generally installed on the trolley guard frame. Because of the angle of collision, inertia and other problems, the trolley fails to stop running in time. Therefore, the present application adds an emergency stop component to the existing trolley guard frame to play the role of early sensing and early stopping. Specifically, in order to sense the deviation of the trolley in advance and ensure timely stopping, we add an extension frame to the trolley guard frame. In this way, under the same inertia conditions, the anti-collision cat whisker can sense the deviation of the trolley at a farther distance, ensuring that the trolley stops at a sufficient distance before hitting the cable machine device. The emergency stop The component adopts a spring whisker design, which can flexibly adjust the sensing distance to adapt to different work scenarios and needs. In the on-site setting, we selected a 500mm long extension frame and set the switch housing at an angle of 45 degrees. After testing, we set the length of the anti-collision whisker to 350mm. When the anti-collision whisker touches the cable and runs to about 90 degrees, it will trigger the switch housing to stop immediately. This design effectively prevents the trolley from colliding with the cable loading device. After many tests and verifications, this anti-collision design can well achieve the expected function and provide a strong guarantee for the safe operation of the tire crane.

[0018] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0019] like Figures 1 to 3 As shown, an emergency stop mechanism includes an emergency stop component 1, which includes an extension frame 101, a switch housing 102, a drive rod 103, a mounting pin 104, a fastening pin 105 and an anti-collision cat whisker 106. The switch housing 102 is fixed to the end of the extension frame 101 by screws, and the drive rod 103 is rotatably mounted on the input end of the switch housing 102. The end of the drive rod 103 is connected to the mounting pin 104, and the root of the mounting pin 104 is fixed to the drive rod 103 by the fastening pin 105. The mounting pin 104 extends outward with an anti-collision cat whisker 106. The extension frame 101 has an extension length of 500 mm, and the end of the extension frame 101 is tilted at an angle of 45 degrees. The length of the anti-collision cat whisker 106 is set to 350 mm, and when the anti-collision cat whisker 106 touches the cable and runs to 90 degrees, it drives the driving rod 103 at the head of the switch housing 102 to rotate through the root mounting pin 104 to change the switch state. When the anti-collision cat whisker 106 touches the cable and runs to about 90 degrees, it triggers the switch housing 102 to move, causing the trolley to stop immediately. This design effectively prevents the trolley from hitting the cable loading device.

[0020] like Figure 1 to Figure 2 As shown, a device for swerving a trolley and hitting a cable machine is installed with the above emergency stop mechanism, including a trolley guard frame 2, the front of the trolley guard frame 2 is fixed to the extension frame 101 by welding, and the trolley guard frame 2 is fixed to the front end of the platform 3, and brackets 4 are fixed on both sides of the rear end of the platform 3, and the brackets 4 are fixed to the back of the trolley guard frame 2 through reinforcing rods 5, and tires 6 are rotatably installed inside the brackets 4 on both sides, and the tires 6 travel on the trolley runway 7;

[0021] It is worth noting that the switch housing 102 of the present application and the driving rod 103 matched with its head adopt the design of the existing mechanical travel switch, and the design of the anti-collision whisker 106 is to extend the sensing distance of the travel switch and play a role of pre-sensing.

[0022] Working principle: At present, anti-collision stop limit devices are generally installed on the trolley guard frame 2. Due to the angle of collision, inertia and other problems, the trolley fails to stop running in time. Therefore, the present application adds an emergency stop component 1 to the existing trolley guard frame 2 to play the role of early sensing and early stopping. Specifically, in order to sense the deviation of the trolley in advance and ensure timely stopping, we have installed an extension frame 101 on the trolley guard frame 2. In this way, under the same inertia conditions, the anti-collision cat whisker 106 can sense the deviation of the trolley at a farther distance, ensuring that the trolley has enough distance to stop before hitting the cable machine device. The emergency stop component 1 adopts a spring The spring whisker design can flexibly adjust the sensing distance to adapt to different working scenarios and needs. In the on-site setting, we selected an extension frame 101 with a length of 500mm and set the switch housing 102 at an angle of 45 degrees. After testing, we set the length of the anti-collision whisker 106 to 350mm. When the anti-collision whisker 106 touches the cable and runs to about 90 degrees, it will trigger the switch housing 102 to stop immediately. This design effectively prevents the trolley from colliding with the cable loading device. After many tests and verifications, this anti-collision design can well achieve the expected function and provide a strong guarantee for the safe operation of the tire 6 crane.
