Abstract

The utility model discloses a crown block anti-collision speed reduction device with a sensitive alarm structure. The crown block anti-collision speed reduction device comprises a bridge frame, and an anti-collision mechanism triggers a hydraulic control switch through a guide rod to control a brake pad so as to slow down the moving speed of a large vehicle body. According to the crown block anti-collision speed reduction device with the sensitive alarm structure, when the two large vehicle bodies are close in the running process, the large vehicle bodies touch the surface of one side of the guide rod, at the moment, the alarm bell trigger switch is triggered, the alarm bell rings to remind a worker to concentrate and operate carefully, and in the process that the guide rod continuously faces inwards, the large vehicle bodies are not prone to collision. When a guide rod reaches the bottom end of the inner wall surface of a sliding groove and triggers an emergency stop button at the same time, the large vehicle body stops moving, the hydraulic rod is driven by the hydraulic rod, the acting force of the hydraulic rod is continuously increased, and therefore the closer the distance between the two large vehicle bodies is, the larger the friction force between a brake pad and a bridge frame is, and the speed reduction effect is achieved. And short-distance collision caused by inertia is prevented, and safety is further ensured.

[0002] Bridge crane is a lifting equipment that is horizontally erected above workshops, warehouses and material yards to lift materials. Because its two ends are located on tall concrete columns or metal brackets, it is shaped like a bridge. The bridge of the bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, and can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and largest type of lifting machinery;

[0003] Multifunctional overhead cranes are frequently used in daily production, and there are often situations where two overhead cranes are close to each other. If the laser anti-collision limit sensor of the crane is not sensitive and the crane operator is not focused, it is easy for the two cranes to collide and create an unsafe situation.

[0006] Preferably, the anti-collision mechanism includes: a guide rod is slidably connected to the inner wall surface of the slide groove, a hydraulic control switch is fixedly connected to the inner wall surface of the guide rod, an emergency stop button is fixedly connected to the inner wall surface of the hydraulic control switch, a positioning plate is fixedly connected to the lower end surface of the large vehicle body, one side surface of the positioning plate is fixedly connected to the outer shell, one side surface of the outer shell is fixedly connected to the bottom plate, the surface of the bottom plate is fixedly connected to a hydraulic rod, and one end surface of the hydraulic rod is fixedly connected to a brake pad.

[0007] By adopting the above technical solution, the anti-collision mechanism solves the problem of accidental collision caused by the insensitive sensing of the laser anti-collision limit of the large vehicle.

[0008] Preferably, an alarm mechanism is provided on the surface of the large vehicle body, wherein the alarm mechanism comprises: a laser rangefinder is fixedly connected to the lower end surface of the large vehicle body, an alarm trigger switch is provided on one side surface of the slide slot, and an alarm is fixedly connected to the one side surface of the vehicle body control box.

[0009] By adopting the above technical solution, the alarm organization solves the problem of accidental collision caused by the staff's lack of concentration.

[0010] Preferably, a hole is provided on the surface of the large vehicle body, and the slide groove is arranged in the hole on the surface of the large vehicle body.

[0011] The above technical solution is adopted to provide a structural basis for the anti-collision mechanism.

[0012] Preferably, one end of the guide rod is fixedly connected to the control handle of the hydraulic control switch, the control handle of the hydraulic control switch is slidingly connected to the inner wall of the main body of the hydraulic control switch, one side surface of the positioning plate is provided with an opening, and the inner wall surface of the opening on one side of the positioning plate is slidingly connected to the outer surface of the brake pad, and one side surface of the brake pad is frictionally connected to one side surface of the bridge frame.

[0013] By adopting the above technical solution, since one end of the guide rod is fixedly connected to the control handle of the hydraulic control switch, as the guide rod continues to move inward, the hydraulic control switch controls the operation of the hydraulic rod on the base plate, so that the force of the hydraulic rod in the outer shell continues to increase, so that the distance between the two large vehicle bodies is closer, the friction between the brake pad in the positioning plate and the bridge frame is greater, thereby achieving the effect of deceleration.

[0014] Preferably, the two laser rangefinders are respectively arranged on two different large vehicle bodies, and the transmitting ends of the laser rangefinders are arranged horizontally.

[0015] By adopting the above technical solution, when two large vehicles are about to collide, the laser rangefinder emits an alarm signal and transmits it to the signal receiver. The signal receiver triggers an alarm bell to remind the staff, and in cooperation with the anti-collision mechanism, the safety hazard is eliminated.

[0016] Preferably, the alarm trigger switch is fixedly mounted on a side surface of the guide rod, and the control end of the alarm is wired and connected to the inside of the signal receiver.

[0017] By adopting the above technical solution, the system can still work normally when the laser anti-collision limit sensor is insensitive. When the laser rangefinder is insensitive, the alarm trigger switch at one end of the guide rod can still trigger the alarm, thereby further ensuring safety.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the overhead travelling crane anti-collision deceleration device with a sensitive alarm structure:

[0019] 1. The anti-collision mechanism solves the problem of accidental collision caused by the insensitive laser anti-collision limit sensor of the large vehicle. When the two large vehicle bodies are close to each other during operation, the large vehicle body touches the surface of one side of the guide rod. At this time, the alarm trigger switch is triggered, and the alarm rings to remind the staff to concentrate and operate carefully. As the guide rod continues to move inward, the hydraulic control switch controls the operation of the hydraulic rod, which increases the friction between the brake pad and the bridge frame, thereby achieving the effect of deceleration, which facilitates the operation of the staff. When the guide rod reaches the bottom of the inner wall surface of the slide, the emergency stop button is triggered at the same time, causing the large vehicle body to stop moving, preventing close-range collisions caused by inertia and further ensuring safety.

[0020] 2. The alarm mechanism solves the problem of accidental collision caused by the staff's lack of concentration. In the actual operation process, the staff's lack of concentration often leads to collision of large vehicles. When two large vehicles are about to collide, the laser rangefinder emits an alarm signal and transmits it to the signal receiver. The signal receiver triggers the alarm bell to remind the staff. With the cooperation of the anti-collision mechanism, the safety hazard is eliminated. The mechanism can still work normally when the laser anti-collision limit sensor is insensitive. When the laser rangefinder is insensitive, the alarm trigger switch at one end of the guide rod can still trigger the alarm bell, thereby further ensuring safety. BRIEF DESCRIPTION OF THE DRAWINGS
