Description

An adjustable guide device for fall protection of a dangling device Technical Field

[0001] This utility model relates to the field of tensioning devices for belt conveyors, and in particular to an adjustable guide device for preventing falls in a vertical tensioning device. Background Technology

[0002] As a core piece of equipment for continuous material transport, the reliability of the tensioning device in a belt conveyor directly affects the system's operational efficiency and safety. After decades of technological evolution, vertical counterweight tensioning devices are commonly used due to their simple structure and adaptive tension adjustment, making them the most widely applied tensioning solution. However, with the increasing complexity of industrial environments and stricter safety standards, the guide rods used to guide and limit the vertical counterweight tensioning device still present some problems in engineering practice:

[0003] First and foremost, the most significant problem is the on-site adaptation difficulties caused by insufficient installation precision. Due to factors such as errors in civil construction and measurement deviations, the preset length of the guide rod often does not match the actual installation height. If the guide rod is too short, it needs to be spliced; if it is too long, it needs to be cut and adjusted. This not only reduces installation efficiency and increases construction costs but also damages the overall integrity and aesthetic consistency of the guide rod.

[0004] Secondly, traditional guide rods are limited by material strength and stability. The design height is usually limited to the range of 3-12 meters. When the conveying system needs to adapt to large tension strokes or high ground drop conditions, the existing guide rods are difficult to meet the strength requirements, and customized height-increasing designs or the use of high-cost reinforcing materials are required, which leads to extended design cycles and increased manufacturing costs, highlighting the contradiction between the structural strength and height limitations of the guide rod.

[0005] Finally, safety protection relies on external equipment, leading to redundant costs. For vertical counterweight tensioning devices installed within the building, traditional solutions require the purchase of separate fall protection buffers to prevent the counterweight from falling and penetrating the floor slab when the tape breaks. Such external equipment not only occupies space and increases procurement and maintenance costs, but also increases system complexity due to its non-integrated design, making it difficult to completely eliminate safety hazards. Summary of the Invention

[0006] To overcome the problems in the background technology mentioned above, this utility model provides an adjustable guide device for preventing falls in a vertical pull device. By setting an adjustable guide device to limit and guide the vertical pull device, the guide device is reinforced and has a built-in buffer module to absorb impact energy. It has the beneficial effects of flexible and adjustable guide rod height, reducing customization costs, enhancing the stability and guiding accuracy of the guide rod structure, integrating safety protection, and reducing reliance on external equipment.

[0007] The technical solution of this utility model is as follows:

[0008] An adjustable guide device for preventing falls in a vertical tensioning device is provided. The guide device is arranged within the limiting structure of the vertical tensioning device. The guide device includes a guide rod body and a telescopic tube. The telescopic tube can move up and down along the guide rod body to adjust its height and is stably connected to the guide rod body through a connecting device.

[0009] Preferably, the limiting structure is provided in two sets, located on both sides of the vertical tensioning device, and each set of limiting structures includes two opposing limiting angle steels.

[0010] More preferably, the guiding device is provided in two sets, and the guide rod body in each set of the guiding device is vertically arranged between the two limiting angle steels of the corresponding limiting structure. The guide body controls the vertical pulling device to move only in the vertical direction by cooperating with the limiting angle steel.

[0011] Preferably, the telescopic tube is a sleeve structure, the guide rod body is a steel pipe structure, and the telescopic tube extends into the guide rod body and is stably connected to it.

[0012] More preferably, the connecting device includes a plurality of bolts evenly arranged circumferentially along the top of the guide rod body, the ends of the bolts passing through threaded holes on the guide rod body and abutting against the surface of the telescopic tube, so that the guide rod body and the telescopic tube remain stably connected.

[0013] More preferably, the guide device is provided in two sets, with the two ends of the horizontally arranged connecting frame connected to the top ends of the two telescopic pipes by means of threaded connection, and the top surface of the connecting frame is fixedly connected to the top foundation.

[0014] More preferably, the height of the guide rod body is in the range of 3-10m, the sleeve length is 600mm, and the vertical distance between the bolt and the top surface of the guide rod body is 200mm.

[0015] Preferably, the guiding device is provided in two sets. Each set of guiding devices has a climbing frame fixed to the outside of the guide rod body. The climbing frame includes a vertical rod parallel to the guide rod body and several horizontal rods fixed between the guide rod body and the vertical rod. The spacing between adjacent horizontal rods is the same.

[0016] More preferably, the bottom ends of the guide rod body and the vertical rod are fixedly connected to the bottom foundation, and a reinforcing steel plate is fixed between the bottom of the guide rod body and the bottom foundation.

[0017] Preferably, the guiding device is provided in two sets, and a horizontally arranged buffer steel plate is fixed below the guide rod body of the two sets of guiding devices. The buffer steel plate is made of shaped steel.

[0018] Compared with existing technologies, the advantages of the above technical solution are as follows:

[0019] (1) By connecting the guide rod body with the telescopic tube, the total length of the guide device can be flexibly adjusted according to the actual installation height requirements, avoiding the problem that traditional guide rods need to be customized to be longer or redundantly cut due to insufficient height, reducing material waste, reducing construction costs, increasing installation costs, and ensuring the integrity and appearance consistency of the guide device.

[0020] (2) By restricting the displacement of the vertical pull device in the horizontal direction, i.e., the front-back and left-right directions, by the guide rod body, the vertical pull device can only move up and down along the guide rod body, thus avoiding excessive displacement of the vertical pull device in the horizontal direction, which would affect the normal function of the hammer pull device and cause the conveyor to fail to transport normally.

[0021] (3) The climbing frame and the bottom foundation can further strengthen the stability of the side of the guide device and improve the overall bending and impact resistance. By setting the reinforcing ribs, the connection stability of the bottom of the guide device is further improved, which solves the problem that the existing guide rods cannot meet the strength requirements. The contradiction between the strength and height of the guide rod structure is prominent, which leads to the need to use customized height design or high-cost reinforcing materials, which increases the design cycle and manufacturing cost.

[0022] (4) The buffer steel plate forms a built-in anti-fall buffer structure. When the tape breaks and the hammer falls, the buffer steel plate can absorb the impact energy, which avoids the hammer falling and penetrating the floor when the tape breaks. It also eliminates the cost of purchasing an anti-fall device as required by traditional solutions, and eliminates the space occupied by external equipment and the complexity of installation, thus realizing the integrated design of safety protection and main structure.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Example 1: As shown in Figures 1 to 3, a fall-prevention adjustable guide device for a vertical tensioning device is provided. This guide device is arranged within the limiting structure of the vertical tensioning device 1. The vertical tensioning device 1 is a vertical counterweight tensioning device, which utilizes the gravity of a counterweight to generate a constant tension force, ensuring the conveyor belt does not slip on the drive roller and guaranteeing the normal operation and safety of the conveyor. Limiting structures are located on both sides of the vertical tensioning device 1, and the guide device is arranged within these structures. With the combined action of the limiting structures and the guide device, the vertical tensioning device 1 can only move up and down along the guide device, preventing excessive horizontal displacement that could affect the normal operation of the conveyor.

[0030] The guiding device includes a guide rod body 2 and a telescopic tube 21. The telescopic tube 21 can move up and down along the guide rod body 2 to adjust its height and is fixedly connected to the guide rod body 2 via a connecting device. In use, the telescopic tube 21 is first adjusted to a suitable height along the length of the guide rod body 2 according to the actual situation, and then the guide rod body 2 and the telescopic tube 21 are stably connected via the connecting device. Therefore, by connecting the guide rod body 2 and the telescopic tube 21, the total length of the guiding device can be flexibly adjusted according to the actual installation height requirements, avoiding the problem of traditional guide rods needing to be customized or redundantly cut due to insufficient height. This reduces material waste, lowers construction costs, increases installation costs, and ensures the integrity and aesthetic consistency of the guiding device.

[0031] Example 2: Based on Example 1, the limiting structure is optimized. There are two sets of limiting structures, located on both sides of the vertical tension device 1. Each set of limiting structures includes two opposing limiting angle steels 11. The two limiting angle steels 11 are arranged vertically with a gap between them. The tops of the limiting angle steels 11 of the two sets of limiting structures are fixedly connected to the hammer pull top cover 12 of the vertical tension device 1 to maintain the overall stability of the vertical tension device 1.

[0032] Furthermore, the guiding device is provided in two sets, as shown in Figures 2 and 3. In each set of guiding devices, the guide rod body 2 is vertically arranged between the two limiting angle steels 11 of the corresponding limiting structure, and the top of the guide rod body 2 extends beyond the top of the limiting angle steel 11. During the process of tightening the conveyor belt, the position of the dangling device 1 will change. At this time, the guide rod body 2 is set between the limiting structures on both sides, so the displacement of the dangling device 1 in the horizontal direction, i.e., the front-back and left-right directions, can be restricted by the guide rod body 2. The dangling device 1 can only move up and down along the guide rod body 2. That is, the guiding device limits and guides the dangling device 1, avoiding excessive displacement of the dangling device 1 in the horizontal direction, which would affect the normal function of the hammer pulling device and cause the conveyor to fail to transport normally.

[0033] Example 3: Based on Example 1, the guiding device is optimized. The telescopic tube 21 is a sleeve structure, and the guide rod body 2 is a steel pipe structure. The bottom end of the telescopic tube 21 extends into the guide rod body 2 and is fixedly connected to it. Specifically, as shown in Figure 1, the connecting device includes several bolts 3 evenly arranged around the top circumference of the guide rod body 2. In this example, there are 4 bolts 3, which are fixed at the front, back, left, and right positions of the guide rod body 2 respectively. In actual use, the telescopic tube 21 is first inserted into the guide rod body 2, and the depth of insertion of the telescopic tube 21 into the guide rod body 2 is adjusted according to the actual situation. After adjustment, the bolts 3 are passed through the corresponding threaded holes on the guide rod body 2 in sequence, and the ends of the bolts 3 are firmly abutted against the surface of the telescopic tube 21. In this way, the connection position of the guide rod body 2 and the telescopic tube 21 can be kept stably connected. By flexibly adjusting the depth of the telescopic tube 21 inserted into the guide rod body 2, the adaptation problem of guide rod length mismatch caused by civil engineering errors is solved, and the on-site installation cycle is significantly shortened.

[0034] Furthermore, the guide device is provided in two sets. The top ends of the telescopic tubes 21 of the two sets of guide devices are fixedly connected by a horizontally arranged connecting frame 22. The two ends of the connecting frame 22 are connected to the top ends of the telescopic tubes 21 by threaded connection. The top surface of the connecting frame 22 is fixedly connected to the top foundation, which is the top structure above the building foundation. This connection structure ensures the connection stability of the top of the guide device.

[0035] Furthermore, the height range of the guide rod body 2 is 3-10m, the sleeve length is 600mm, and the vertical distance between the position of the mounting bolt 3 on the guide rod body 2 and the top surface of the guide rod body 2 is 200mm. That is, the sleeve must be inserted into the guide rod body 2 by at least 200mm in order to stably connect the two by the bolt 3. Thus, the height adjustment range of the guide device is from the height of the guide rod body 2 to the height of the guide rod body 2 plus 400mm. This adjustment range can solve most problems caused by the mismatch between the preset length of the guide rod and the actual installation height.

[0036] Example 4: Based on Example 1, a preferred design is implemented. The guide device comprises two sets. Each set has a climbing frame 4 fixed to the outer side of the guide rod body 2. The climbing frame 4 includes a vertical rod 41 parallel to the guide rod body 2 and several horizontal rods 42 fixed between the guide rod body 2 and the vertical rod 41. The spacing between adjacent horizontal rods 42 is the same. The two ends of the horizontal rods 42 are welded to the guide rod body 2 and the vertical rod 41 respectively. The climbing frame design facilitates installation operations by allowing construction personnel to climb onto the guide device via the climbing frame 4, providing a safe climbing path for maintenance personnel and reducing the risks of high-altitude maintenance operations.

[0037] Furthermore, the bottom ends of the guide rod body 2 and the vertical rod 41 are fixedly connected to the bottom foundation. The bottom foundation is the structural part of the building's bottom and a component connecting the foundation and the main structure of the building. In this embodiment, the bottom ends of both the guide rod body 2 and the vertical rod 41 are fixedly connected to the bottom foundation. That is, the climbing frame 4 being fixed to the bottom foundation further strengthens the overall stability of the guiding device and improves its overall bending and impact resistance. A reinforcing steel plate 23 is fixed between the bottom of the guide rod body 2 and the bottom foundation. This reinforcing plate is an angle steel structure, and the connection stability of the bottom of the guiding device is further improved by setting the reinforcing plate.

[0038] Example 5: Based on Example 1, an optimized design is made. The guide device is provided in two sets. Horizontally arranged buffer steel plates 5 are fixed below the guide rod body 2 of the two sets of guide devices. The two sides of the buffer steel plates 5 are welded and fixed to the rod body of the guide rod body 2. The buffer steel plates 5 are made of shaped steel. The setting of the buffer steel plates 5 forms a built-in anti-fall buffer structure. When the tape breaks and the hammer falls, the buffer steel plates 5 can absorb the impact energy, avoiding the hammer falling and penetrating the floor when the tape breaks. It also eliminates the cost of additional anti-fall devices required by traditional solutions, and eliminates the space occupation and installation complexity of external equipment, realizing the integrated design of safety protection and main structure.

[0039] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the technical solution of this application, and these all fall within the scope of protection of this application.
