Description

Technical Field

[0001] This utility model relates to the field of stacker-reclaimer technology, specifically a dual anti-collision protection device for stacker-reclaimers. Background Technology

[0002] With the rapid development of science and technology and the economy, material transportation is becoming more and more frequent. One of the more commonly used pieces of equipment in material transportation is the bucket wheel stacker-reclaimer. The bucket wheel stacker-reclaimer is a high-efficiency loading and unloading machine used in large dry bulk cargo yards, which can both stack and reclaim materials. It consists of a belt conveyor arm that can tilt and swing horizontally, as well as the bucket wheel at its front end, the frame, and the running mechanism. The belt can run in both directions. When reclaiming materials, the bucket wheel picks up the materials and sends them out through the conveyor arm. When stacking materials, the goods transported by the main conveyor are thrown into the yard through the conveyor arm. The conveyor arm of the stacker-reclaimer is relatively long, and it is necessary to avoid collisions with surrounding objects when it rotates.

[0003] Among them, Chinese patent with announcement number CN202807906U discloses a collision avoidance control system for a boom, a stacker, a reclaimer and a stacker-reclaimer. It uses a suspended tilt switch as the trigger device for collision avoidance protection. The tilt switch does not require manual reset by the operator, saving operation time and greatly improving the working efficiency of the equipment.

[0004] The above-mentioned solution uses a suspended tilt switch as an anti-collision protection method. Although it can achieve automatic reset, it lacks a mechanical protective structure and can still result in direct collisions when forced by external force, making it difficult to provide adequate protection at the collision point. Therefore, we provide a dual anti-collision protection device for stacker-reclaimers to solve the above problems. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a dual anti-collision protection device for stacker-reclaimers.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a dual anti-collision protection device for a stacker-reclaimer, comprising:

[0009] A boom, one end of which is mounted on a stacker-reclaimer.

[0010] The connector is H-shaped, with a first cavity and a second cavity formed on both sides. The connector is detachably mounted on the boom through the second cavity, and a laser rangefinder is installed in the first cavity.

[0011] Two abutment members are respectively disposed above and below the first cavity, and the first cavity is provided with a connecting component for elastically supporting the abutment members.

[0012] Furthermore, the connecting seat is equipped with two sets of fixing bolts, and the fixing bolts are threadedly connected to the boom.

[0013] Furthermore, the connecting assembly includes two sliders, and the connecting seat has two guide grooves. The two sliders are slidably connected in the two guide grooves respectively. A connecting shaft is rotatably connected to each of the two sliders, and the connecting shaft is fixedly connected to the abutment.

[0014] Furthermore, a guide rod is fixedly connected inside the guide groove, and the slider is slidably connected to the guide rod. A buffer spring is sleeved on the guide rod, and the two ends of the buffer spring abut against the slider and the inner wall of the guide groove, respectively.

[0015] Furthermore, a rubber ring is fixedly connected to the abutment.

[0016] Furthermore, the abutment is circular, and a gap is left between the abutment and the connecting seat.

[0017] (iii) Beneficial effects:

[0018] Compared with existing technologies, this stacker-reclaimer's dual anti-collision protection device has the following advantages:

[0019] I. This utility model, by installing a laser rangefinder in the first cavity of the connecting seat, can monitor the surrounding environment in real time and provide early warning of possible collisions. Combined with the abutment and buffer spring in the mechanical protection structure, when an external force approaches, it can not only detect potential dangers in advance, but also effectively unload and buffer the force when in actual contact, avoiding damage to the equipment caused by direct collisions, and greatly improving the safety and reliability of the anti-collision system.

[0020] Second, this utility model adopts a mechanical protection structure with automatic reset function, that is, when there is an inclined contact, the force can be discharged by rotation and the impact force can be absorbed by the buffer spring. This not only reduces the operation interruption caused by collision, but also reduces the risk of damage to the components, thereby improving the working efficiency of the stacker-reclaimer.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-3 As shown, this utility model provides a technical solution: a dual anti-collision protection device for a stacker-reclaimer, including a boom 1, a connecting seat 2, and two abutment parts 3.

[0027] One end of boom 1 is installed on the stacker-reclaimer. Since boom 1 is a moving part on the stacker-reclaimer, it needs to be rotated or tilted during adjustment to complete the stacking or removal of materials.

[0028] In this embodiment, the connecting seat 2 is H-shaped, and a first cavity 5 and a second cavity 6 are formed on both sides of the connecting seat 2. The connecting seat 2 is detachably installed on the boom 1 through the second cavity 6. A laser rangefinder 7 is installed in the first cavity 5. The laser rangefinder 7 is an existing structure and the model is not limited. It can monitor the presence of objects in the surrounding area and the distance between the objects and the boom 1 in real time by emitting laser. Moreover, the number of connecting seats 2 can be increased according to actual needs.

[0029] The connecting seat 2 is equipped with two sets of fixing bolts 8, and the fixing bolts 8 are threadedly connected to the boom 1. The boom 1 is designed with screw holes that match the fixing bolts 8. When fixing the connecting seat 2, one end of the fixing bolt 8 needs to be installed in the screw hole to complete the fixing of the connecting seat 2.

[0030] Two abutment members 3 are respectively disposed above and below the first cavity 5, and the first cavity 5 is provided with a connecting component for elastically supporting the abutment members 3.

[0031] In this embodiment, the connecting assembly includes two sliders 10, and two guide grooves 9 are provided on the connecting seat 2. The two sliders 10 are slidably connected in the two guide grooves 9 respectively. A connecting shaft 11 is rotatably connected to each of the two sliders 10, and the connecting shaft 11 is fixedly connected to the abutment 3.

[0032] Since the abutment 3 is rotatably mounted on the slider 10 via the connecting shaft 11, when an external force contacts the abutment 3 at an angle, the abutment 3 will deflect the force by rotating, thus avoiding a large impact force due to hard contact. The force of direct collision will cause the abutment 3 to drive the slider 10 to move within the guide groove 9 via the connecting shaft 11, thereby buffering the impact force.

[0033] A guide rod 12 is fixedly connected inside the guide groove 9, and the slider 10 is slidably connected to the guide rod 12. A buffer spring 13 is sleeved on the guide rod 12. The two ends of the buffer spring 13 abut against the slider 10 and the inner wall of the guide groove 9, respectively. The buffer spring 13 can buffer the impact force borne by the slider 10.

[0034] A rubber ring 4 is fixedly connected to the abutment 3. The abutment 3 is circular, and there is a gap between the abutment 3 and the connecting seat 2. By using a circular abutment 3, it is convenient for the abutment 3 to rotate and relieve force.
