Description

Technical Field

[0001] This utility model relates to the field of tipper maintenance technology, and in particular to a modular suspension combination bracket for maintaining the bottom of the coal grate of a tipper. Background Technology

[0002] The coal grate of a tipper is a key component installed below the tipper, on top of the receiving hopper or silo. Its distance from the bottom of the hopper or silo is generally greater than 5 meters. Its core function is to perform preliminary screening and protection of unloaded coal or other bulk materials. The tipper coal grate is an inclined component with multiple square openings, typically 200–400 mm wide, constructed from parallel steel bars or I-beams welded together. Regular inspection and maintenance of the tipper coal grate are required during use, including welding reinforcement, cable and vibrator repair.

[0003] For the inspection and maintenance of the bottom of the coal grate, existing technology typically involves lowering workers through an inspection hole into the grate using a steel wire rope anchored at anchor points and a suspended frame. However, the steel wire rope and suspended frame have limited range of motion and are prone to swaying, increasing the risk of slips or falls. Furthermore, this method only allows for the inspection of the grate and vibrators around the inspection hole. Another approach is to erect scaffolding at the bottom of the receiving hopper or bin, allowing workers to stand directly above the grate for inspection and maintenance. While this method offers some safety and a large inspection area, scaffolding installation is time-consuming and labor-intensive, and the presence of conveyor belts at the bottom of the receiving hopper or bin further complicates the scaffolding setup. Utility Model Content

[0004] Therefore, it is necessary to provide a modular suspension combination bracket for inspecting the bottom of the coal grate of a tipper, which has a wide inspection range, is easy to disassemble and assemble, and can improve the safety of tipper coal grate maintenance personnel.

[0005] This utility model provides a modular suspension combination bracket for inspecting the bottom of the coal grate of a tipper, including at least three bracket units that can be suspended from the bottom of the coal grate of the tipper;

[0006] Each support unit includes a first lifting rod, a second lifting rod, a pedal, and a locking mechanism. The first and second lifting rods are both vertically arranged, with equal lengths and flush tops. The tops of both the first and second lifting rods are integrally fixedly connected to a U-shaped hook that can vertically hook onto the horizontal part of the coal grate opening of the tipper. The opening of the U-shaped hook faces downwards and its sidewall is perpendicular to the top.

[0007] The bottom ends of both the first and second booms are provided with threaded portions of length L. The threaded portions have external threads and are inserted into the pedal, which is perpendicular to the first boom.

[0008] The locking mechanism is used to restrict the downward movement of the pedal and includes a first locking nut and a second locking nut. The first locking nut is threadedly connected to the threaded part of the first rod, and the second locking nut is threadedly connected to the threaded part of the second rod. The tops of both the first locking nut and the second locking nut abut against the bottom of the pedal.

[0009] In one embodiment, the pedal is provided with two mounting holes, and the threaded portions of the first and second rods are both inserted into one mounting hole.

[0010] In one embodiment, the modular suspension assembly support for inspecting the bottom of the tipper coal grate also includes a safety protection component, which is used to connect all support units in the horizontal direction as a modular suspension assembly support with a bus topology.

[0011] The safety protection components include a safety rope and buckles that are fixedly connected to both ends of the safety rope;

[0012] A safety ring is fixedly connected to the middle of the first suspension rod of each support unit. One end of the safety rope is connected to the safety ring of the first support unit of the modular suspension combination support with a bus topology through a buckle, and the other end passes through the safety rings of all the intermediate support units and is connected to the safety ring of the last support unit.

[0013] In one embodiment, the first support unit of the modular suspension combination support with a bus topology is defined as the main support unit. The main support unit is suspended below the inspection hole of the tipper coal grate. The second rod of the main support unit is arranged with multiple horizontal plates in a vertical array, and each horizontal plate is vertically fixedly connected to the second rod of the main support unit.

[0014] In one embodiment, baffles are vertically fixed around the pedal, and both the pedal and the baffles are perforated steel plates. The upper surface of the pedal is provided with anti-slip texture.

[0015] In one embodiment, a reinforcing rod is fixedly connected between the U-shaped hooks of the first and second rods of any support unit, and the reinforcing rod is perpendicular to both the first and second rods.

[0016] In one embodiment, L is 30cm to 60cm;

[0017] The horizontal distance between the first and second hangers of any support unit is 40cm to 60cm.

[0018] The vertical distance between two adjacent horizontal boards is 25cm to 30cm.

[0019] The beneficial effects of this utility model are:

[0020] (1) The modular suspension combination bracket for overhauling the bottom of the coal grate of the tipper can be flexibly combined by selecting different numbers of modular bracket units according to different maintenance scopes, and is applicable to a wide range of maintenance.

[0021] (2) The support unit of this utility model can be vertically hooked onto the horizontal part of the coal grate hole of the tipper by a U-shaped hook, which is convenient and quick to install;

[0022] (3) The opening of the U-shaped hook faces downward and the side wall is perpendicular to the top. The horizontal part of the coal grate of the tipper is a steel plate with a vertical setting and a horizontal top. When the U-shaped hook is vertically hooked onto the horizontal part of the coal grate of the tipper, the entire support unit is not easy to shake, which improves the safety of the tipper coal grate maintenance personnel.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] It should be noted that in the description of this utility model, "upper," "lower," "top," "bottom," and orientation or positional relationship are based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In one embodiment, such as Figure 1 As shown, the modular suspension combination bracket used for inspecting the bottom of the tipper coal grate in this embodiment includes at least three bracket units 1 that can be suspended at the bottom of the tipper coal grate.

[0031] Each support unit 1 includes a first lifting rod 11, a second lifting rod 12, a pedal 13, and a locking mechanism 14. The first lifting rod 11 and the second lifting rod 12 are both vertically arranged. The first lifting rod 11 and the second lifting rod 12 are of equal length and their top ends are flush. The top ends of the first lifting rod 11 and the second lifting rod 12 are integrally fixedly connected to a U-shaped hook 111 that can vertically hook onto the horizontal part of the coal grate opening of the tipper. The opening of the U-shaped hook 111 faces downward and its side wall is perpendicular to the top.

[0032] Preferably, the lengths of the first boom 11 and the second boom 12 are 2m to 2.2m, and when the pedal 13 is installed, it is necessary to ensure that maintenance personnel can stand upright under the coal grate of the tipper.

[0033] Specifically, the horizontal part of the tipper coal grate is a vertically set steel plate with a horizontal top. The opening of the U-shaped hook 111 faces downward and the side wall is perpendicular to the top. Therefore, the U-shaped hook 111 has good stability after being connected to the tipper coal grate, which can increase the safety and reliability of the support unit 1 and ensure the safety of maintenance personnel.

[0034] The bottom ends of the first boom 11 and the second boom 12 are each provided with a threaded portion 112 of length L. The threaded portion 112 has external threads and is inserted into the pedal 13, which is perpendicular to the first boom 11. L is 30cm to 60cm.

[0035] The step 13 is vertically mounted to the two booms to provide a support platform for maintenance personnel to stand on below the coal grate of the tipper.

[0036] The locking mechanism 14 is used to restrict the downward movement of the pedal 13. It includes a first locking nut 141 and a second locking nut 142. The first locking nut 141 is threadedly connected to the threaded portion 112 of the first rod 11, and the second locking nut 142 is threadedly connected to the threaded portion 112 of the second rod 12. The tops of the first locking nut 141 and the second locking nut 142 abut against the bottom of the pedal 13.

[0037] Specifically, the pedal 13 is provided with two mounting holes 131, and the threaded portions 112 of the first rod 11 and the second rod 12 are both inserted into one mounting hole 131. The pedal 13 can slide up and down relative to the first rod 11 and the second rod 12, and the downward movement of the pedal 13 is restricted by two locking nuts. That is, in this embodiment, the height of the pedal 13 relative to the U-shaped hook 111 is adjustable.

[0038] It should be noted that in this embodiment, a locking nut can be provided on the upper part of the pedal 13 relative to the position of the first locking nut 141 and the second locking nut 142 respectively. By locking the pedal 13 with the upper and lower locking nuts, the stability between the pedal 13 and the first rod 11 and the second rod 12 can be increased.

[0039] This embodiment features a modular suspension support for inspecting the bottom of the tipper's coal grate. Support unit 1, being a modular structure, can be assembled in varying numbers to suit different maintenance needs. This device is suitable for different applications and offers flexible assembly. Furthermore, in this embodiment, support unit 1 only requires hooking the U-shaped hook 111 onto the horizontal part of the tipper's coal grate openings to install the coal grate support, making installation quick, convenient, and easy.

[0040] In one embodiment, the modular suspension assembly bracket for inspecting the bottom of the tipper coal grate also includes a safety protection component 2, which is used to connect all the support units 1 in the horizontal direction to form a modular suspension assembly bracket with a bus topology.

[0041] The safety protection component 2 includes a safety rope 21 and buckles fixedly connected to both ends of the safety rope 21. A safety ring 22 is fixedly connected to the middle of the first rod 11 of each support unit 1. One end of the safety rope 21 is connected to the safety ring 22 of the first support unit 1 of the modular suspension combination support with a bus topology through the buckle, and the other end passes through the safety rings 22 of all the intermediate support units 1 and is connected to the safety ring 22 of the last support unit 1.

[0042] Specifically, safety rope 21 is a steel cable. The function of safety rope 21 is to assist maintenance personnel in moving between different support units 1. Furthermore, safety rope 21 can be used in conjunction with the safety harness worn by maintenance personnel to prevent slips or falls due to improper positioning. Specifically, the buckle of the safety harness worn by the maintenance personnel is attached to safety rope 21. When maintenance personnel move between different support units 1, safety rope 21 continuously provides preventative protection.

[0043] It should be noted that the topology of all support units 1 connected in the horizontal direction is not limited to a bus type. Those skilled in the art can make specific adjustments according to actual needs, and the number of safety protection components 2 can also be adjusted accordingly.

[0044] In one embodiment, such as Figure 2As shown, the first support unit 1 of the modular suspension combination support with a bus topology is defined as the main support unit 1. The main support unit 1 is suspended below the inspection hole of the coal grate of the tipper. The second hanger 12 of the main support unit 1 is arranged with multiple horizontal plates 3 in a vertical array. Each horizontal plate 3 is vertically fixedly connected to the second hanger 12 of the main support unit 1.

[0045] Specifically, the vertical distance between two adjacent horizontal plates 3 is 25cm to 30cm.

[0046] The inspection hole is a hole on the coal grate that allows maintenance personnel to pass through. The second hanger 12 of the main support unit 1 is arranged with multiple horizontal plates 3 in a vertical array. The multiple horizontal plates 3 serve as a ladder, making it convenient for maintenance personnel to go down from the inspection hole to the step plate 13.

[0047] In one embodiment, such as Figure 3 As shown, baffles 4 are vertically fixed around the pedal 13. Both the pedal 13 and the baffles 4 are perforated steel plates, and the upper surface of the pedal 13 is provided with anti-slip texture.

[0048] The baffle 4 is used to provide further protection. Both the pedal 13 and the baffle 4 are made of perforated steel plates, which can reduce the weight of the pedal 13 and reduce the installation weight of the bracket unit 1. The anti-slip texture can increase the friction of the pedal 13 and prevent maintenance personnel from slipping.

[0049] In one embodiment, such as Figure 4 As shown, a reinforcing rod 5 is fixedly connected between the U-shaped hooks 111 of the first rod 11 and the second rod 12 of any support unit 1. The reinforcing rod 5 is perpendicular to both the first rod 11 and the second rod 12.

[0050] The function of the reinforcing rod 5 is to enhance the connection between the two suspension rods, further improve the stability of the support unit 1, reduce the swaying of the support unit 1, and improve the safety of the entire modular suspension assembly support.

[0051] In one embodiment, the horizontal distance between the first hanger 11 and the second hanger 12 of any support unit 1 is 40cm to 60cm, which facilitates maintenance personnel to pass between the two hangers and concentrates the gravity applied by the maintenance personnel to each hanger of the chain in the middle of the two hangers, thereby reducing the swaying of the support unit 1.

[0052] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
