Description

Technical Field

[0001] The present invention relates to the technical field of overhaul of tippers, and particularly to a modular hanging combined bracket for overhauling the bottom of the coal grate of a tipper. Background Art

[0002] The coal grate of a tipper is a key component installed below the tipper and at the top of the receiving hopper or silo. The distance from it to the bottom of the receiving hopper or silo is generally greater than 5m. Its core function is to conduct preliminary screening and protection on the unloaded coal or other bulk materials. The coal grate of a tipper is an inclined component composed of parallel steel bars or I-beams welded together with multiple square pores. The width of the square pores is usually 200 - 400mm. During the use of the coal grate of a tipper, regular overhaul and maintenance are required, including welding reinforcement, cable and vibrator overhaul, etc.

[0003] For the overhaul and maintenance of the bottom of the coal grate, in the prior art, usually, the operating personnel are lowered to the bottom of the coal grate through the inspection hole by a wire rope fixed by an anchor point combined with a hanging frame. However, due to the limited movement range and swaying of the wire rope combined with the hanging frame, it is easy to occur slip or fall accidents, and only the coal grate and vibrator around the inspection hole can be overhauled. In addition, there is another method, which is to build a scaffolding at the bottom of the receiving hopper or silo, and the operating personnel directly stand above the coal grate to overhaul and maintain the bottom of the coal grate. Although this method has a certain safety and a large overhaul range, the installation of the scaffolding is time-consuming and laborious, and there is usually a belt conveyor at the bottom of the receiving hopper or silo, and it is not convenient to build the scaffolding.

[0030] In one embodiment, as Figure 1 shown, in this embodiment, the modular hanging combined bracket for overhauling the bottom of the dumper coal grate includes at least three bracket units 1 that can be hung under the bottom of the dumper coal grate.

[0031] Each bracket unit 1 includes a first suspension rod 11, a second suspension rod 12, a pedal 13 and a locking mechanism 14. The first suspension rod 11 and the second suspension rod 12 are both vertically arranged. The first suspension rod 11 and the second suspension rod 12 are equal in length and their tops are flush. At the tops of the first suspension rod 11 and the second suspension rod 12, a U-shaped hook 111 that can vertically hook the horizontal part of the pore of the dumper coal grate is integrally fixed. The opening of the U-shaped hook 111 faces downward and the side wall is perpendicular to the top.

[0032] Preferably, the length of the first suspension rod 11 and the second suspension rod 12 is 2m to 2.2m. When installing the pedal 13, it is necessary to ensure that maintenance personnel can stand upright under the dumper coal grate.

[0033] Specifically, the horizontal part of the pore of the dumper coal grate is a vertically arranged 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. After the U-shaped hook 111 is connected to the dumper coal grate, the stability is good, which can increase the safety and reliability of the bracket unit 1 and ensure the safety of maintenance personnel.

[0034] Threaded parts 112 with a length of L are provided at the bottoms of the first suspension rod 11 and the second suspension rod 12. The threaded parts 112 have external threads. The threaded parts 112 are inserted into the pedal 13, and the pedal 13 is perpendicular to the first suspension rod 11. L is 30cm to 60cm.

[0035] Among them, the pedal 13 is perpendicular to the two suspension rods and is used to provide a support standing plane for maintenance personnel under the dumper coal grate.

[0036] The locking mechanism 14 is used to limit the downward movement of the pedal 13 and includes a first locking nut 141 and a second locking nut 142. The first locking nut 141 is threadedly connected to the threaded part 112 of the first suspension rod 11, and the second locking nut 142 is threadedly connected to the threaded part 112 of the second suspension rod 12. The tops of the first locking nut 141 and the second locking nut 142 are both abutted against the bottom of the pedal 13.

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

[0038] It should be noted that in this embodiment, a locking nut can be respectively provided at the positions of the upper direction of the pedal 13 relative to the first locking nut 141 and the second locking nut 142. The pedal 13 is locked by the upper and lower locking nuts, which can increase the stability between the pedal 13 and the first suspension rod 11 and the second suspension rod 12.

[0039] The modular suspension combined bracket for overhauling the bottom of the coal grate of the dumper in this embodiment, the bracket unit 1 is a modular structure, and different numbers of splicing can be carried out according to different overhaul and maintenance scopes to obtain a combined bracket suitable for the scope to be overhauled. This device is applicable to different ranges and is flexible to assemble. In addition, the bracket unit 1 of this embodiment only needs to hook the horizontal part of the pore of the coal grate of the dumper through the U-shaped hook 111 to realize the installation of the coal grate bracket, and the installation is fast and convenient, and the deployment difficulty is low.

[0040] In one of the embodiments, the modular suspension combined bracket for overhauling the bottom of the coal grate of the dumper further includes a safety protection component 2, and the safety protection component 2 is used to connect all the bracket units 1 in the horizontal direction into a modular suspension combined bracket with a bus topology relationship. [[ID=⑧]]

[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 suspension rod 11 of each bracket unit 1. One end of the safety rope 21 is connected to the safety ring 22 of the first bracket unit 1 of the modular suspension combined bracket with a bus topology relationship through a buckle, and the other end passes through the safety rings 22 of all the intermediate bracket units 1 and then is connected to the safety ring 22 of the last bracket unit 1.

[0042] Specifically, the safety rope 21 is a steel wire rope. The function of the safety rope 21 is to assist maintenance personnel to walk on different bracket units 1. In addition, the safety rope 21 can further cooperate with the safety rope 21 worn by the maintenance personnel to prevent accidents such as slipping or falling caused by improper standing positions of the maintenance personnel. Specifically, the buckle of the safety belt worn by the maintenance personnel is sleeved on the safety rope 21, and when the maintenance personnel move on different bracket units 1, the safety rope 21 continuously provides preventive protection for the maintenance personnel.

[0043] It should be noted that the topological relationship of the connection of all the bracket units 1 in the horizontal direction is not limited to the bus type, and those skilled in the art can make specific adjustments according to actual needs, and the number of the safety protection components 2 can also be specifically adjusted.

[0044] In one of the embodiments, as Figure 2As shown in the figure, the first bracket unit 1 of the modular suspension combined bracket with a bus-type topological relationship is defined as the main bracket unit 1. The main bracket unit 1 is suspended below the inspection hole of the dumper coal grate. A plurality of cross plates 3 are arranged in an array along the vertical direction on the second suspension rod 12 of the main bracket unit 1, and each cross plate 3 is fixedly connected to the second suspension rod 12 of the main bracket unit 1 perpendicularly.

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

[0046] The inspection hole is a hole on the coal grate through which maintenance personnel can pass. A plurality of cross plates 3 are arranged in an array along the vertical direction on the second suspension rod 12 of the main bracket unit 1. The plurality of cross plates 3 serve as a ladder to facilitate maintenance personnel to descend from the inspection hole to the pedal 13.

[0047] In one embodiment, as Figure 3 shown in the figure, baffles 4 are fixedly connected perpendicularly around the pedal 13. Both the pedal 13 and the baffles 4 are perforated steel plates, and anti-slip patterns are provided on the upper surface of the pedal 13.

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

[0049] In one embodiment, as Figure 4 shown in the figure, a reinforcing rod 5 is fixedly connected between the U-shaped hooks 111 of the first suspension rod 11 and the second suspension rod 12 of any one bracket unit 1, and the reinforcing rod 5 is perpendicular to both the first suspension rod 11 and the second suspension 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 bracket unit 1, reduce the sway of the bracket unit 1, and improve the safety of the entire modular suspension combined bracket.

[0051] In one embodiment, the horizontal distance between the first suspension rod 11 and the second suspension rod 12 of any one bracket unit 1 is 40 cm to 60 cm, which is convenient for maintenance personnel to pass through between the two suspension rods, enabling the gravity exerted by the maintenance personnel on each suspension rod to be concentrated in the middle of the two suspension rods, reducing the sway of the bracket unit 1.

[0052] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
