Description

Technical Field

[0001] The present application belongs to the technical field of automatic antifreeze liquid spraying equipment, and specifically is a new type of antifreeze liquid spraying device used in a compact space. Background Art

[0002] As a special equipment, the antifreeze automatic spraying system is especially suitable for use in coal washing plants and railway transportation units in northern my country in winter. The rapid loading station of the coal washing plant shoulders the heavy responsibility of product export, which can be said to be the throat of production. The loading efficiency and loading quality have a great impact on the normal production of the coal preparation plant. Train transportation requires not only fast and accurate loading but also fast unloading at ports, platforms and other stations. In winter, antifreeze spraying becomes the top priority of loading work. When spraying antifreeze for railway coal transportation, you need to choose the right time. Generally, spraying is carried out before the vehicle departs to ensure that the coal and transportation equipment are not frozen.

[0003] When spraying antifreeze, the amount needs to be controlled and evenly covered. Too much antifreeze may pollute the coal, and too little antifreeze will not have an antifreeze effect, so it is necessary to spray an appropriate amount according to the actual situation. On the one hand, when the amount of antifreeze sprayed is the same, the closer the spraying point is to the loading point, the less antifreeze will be lost from the inner wall and bottom of the carriage during the movement of the coal transport train, the better the antifreeze effect, and the less pollution the lost antifreeze will cause to the train line. On the other hand, when the antifreeze spraying equipment is spraying, the nozzle is suspended 200mm above the carriage, and the size of the wind has a great influence on the spraying effect. In the case of strong winds in winter, the antifreeze will inevitably drift out of the carriage with the wind during the spraying process, and the spraying will also have a directionality with the wind, which will not only cause a waste of antifreeze, but also affect the spraying quality of the antifreeze in the carriage and pollute the environment. Therefore, if the on-site conditions permit, it is best to install the antifreeze spraying equipment near the silo in the loading station. In this way, the spraying distance is close to the loading station and the equipment is installed in the loading station, which can greatly reduce the impact of strong winds on the spraying effect. It perfectly takes into account the above two issues. On the premise that the spraying volume can meet the requirements of the railway transportation department, it improves the coal transportation efficiency while reducing energy waste and environmental pollution.

[0004] However, the bottom tracks of the loading station are usually supported by concrete columns on both sides. The space is limited and observation platforms are arranged along the tracks in the station relying on concrete columns for observers to walk on and cross the lanes. In addition, the equipment is heavy and not suitable for installation on the observation platform. Therefore, the spraying equipment can only be placed outside the loading station and fixed on a special maintenance platform. Summary of the invention

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0040] like Figure 1 and Figure 5 As shown, a new antifreeze liquid spraying device used in a compact space comprises:

[0041] Column 1;

[0042] A swivel arm 15, one end of which is mounted on the top of the column 1 and can rotate around the top of the column 1;

[0043] An L-shaped bracket 14, wherein the upper end of the L-shaped bracket 14 is fixedly connected to the slewing arm 15, and the other end of the L-shaped bracket 14 is connected to the column 1 and can rotate around the column 1;

[0044] A slewing device 13, wherein the slewing device 13 drives the slewing arm 15 to rotate around the column 1;

[0045] A base 3, wherein the base 3 is installed at the bottom of the column 1 and supports the column 1, and the base 3 is fixed on the cement column 2;

[0046] A spraying device is installed on the rotating arm 15.

[0047] The utility model changes the floor-standing installation mode of the original structure into a cantilever installation mode. The column 1 is installed on the base 3, and is fastened to the cement column 2 through the base 3.

[0048] In some embodiments, Figure 2 , 3 As shown in , 4, the base 3 includes:

[0049] The clamping structure comprises: two clamping plates 8, the two clamping plates 8 are symmetrically arranged on both sides of the cement column 2; two stud bolt groups 9, the two stud bolt groups 9 are symmetrically passed through the two clamping plates 8; two connecting plates 11, the two connecting plates 11 are symmetrically installed on one of the clamping plates 8;

[0050] The column connection structure includes: two supporting ribs 6, which are respectively fixed to two connecting plates 11 by bolt groups 7; and a mounting base plate 5, which is fixed on the top of the two supporting ribs 6 and is used to be fixed to the column 1.

[0051] In some embodiments, a rib 10 is disposed on the clamping plate 8 .

[0052] In some embodiments, a bolt hole is provided in the middle of the clamping plate 8 , an expansion bolt 12 is provided in the bolt hole, and the clamping plate 8 is fixed to the cement column 2 through the expansion bolt 12 .

[0053] Since the overall installation and rotation process is carried out on the observation platform 9, the space is compact and can only accommodate two workers working at the same time. The structure of the base 10 should be light and easy to install on site while taking safety into consideration. Therefore, the structure of the base 10 is designed to consist of two parts, one is the clamping structure part, and the other is the equipment column connection part, and the two parts are connected by a bolt group 14. The clamping structure part is composed of a clamping plate 15 on each side to clamp the cement column 11 through a stud group 16. Two connecting plates 17 are welded on the clamping plate 15 on the installation side of the column 1, and are connected to the two supporting ribs 13 under the equipment installation base plate 12 through a bolt group 14, so as to achieve the purpose of supporting the spraying equipment. At the same time, in order to reduce the deformation problem of the clamping plate 15 caused by welding and local locking, 4 anti-deformation ribs 18 are welded on the clamping plate 15 on each side. Moreover, the connection plate 17 and the clamping plate 15 on the equipment installation side are cut into a serrated shape and inserted into the four rib plates 18 on the equipment installation side, which increases the welding length and makes the base stronger as a whole. At the same time, in order to improve the safety performance, an expansion bolt 19 is nailed between the clamping plates 15 on both sides and the concrete columns 11 to prevent the base from slipping and increase the overall installation reliability.

[0054] In some embodiments, the rotating device 13 includes:

[0055] A reducer 19, the reducer 19 is fixed on a support base 20, and the support base 20 is fixed on an L-shaped bracket 14;

[0056] A large gear 22 is fixed on the column 1.

[0057] The small gear 21 is connected to the output shaft of the speed reducer 19 and meshes with the large gear 22 .

[0058] Specifically, after the reducer 19 is started, it drives the small gear 21 to rotate. Since the large gear 22 is fixed on the column 1 and does not move, the small gear 21 makes a circular motion around the large gear 22, that is, the rotating device 13 and the L-shaped bracket 14 rotate around the column 1 as a whole, thereby driving the rotating arm 15 to rotate. The reducer 19 controls the rotating arm 15 to rotate out or back in in the forward and reverse rotation.

[0059] One end of the L-shaped bracket 14 connected to the column 1 is equipped with a roller 23, which is embedded in a raceway 24, and the raceway 24 is fixed on the column 1. It plays a supporting role and can effectively ensure that the slewing arm 15 moves stably under severe weather conditions.

[0060] In some embodiments, the spraying device includes: a lifting device 16, which is installed at the front end of the rotating arm 15; a nozzle group 17, which is installed at the lower end of the lifting device 16, and the nozzle group 17 is connected to the antifreeze source through a pipeline 18.

[0061] The lifting device 16 is responsible for adjusting the height direction of the nozzle group 17 to cope with the spraying work of train carriages of different heights. The swivel arm 15 can swivel around the column 1 in any direction and at any angle. Since the swivel arm 15 is long and the weight at the end is large, an L-shaped bracket 14 is added for the consideration of swivel stability. One end of the L-shaped bracket 14 is fastened to the swivel arm 15, and the other end is equipped with a roller. When the swivel arm 15 rotates, the roller rolls on the column 1 to play a supporting role. The L-shaped bracket 14 is equipped with a swivel device 13.

[0062] The slewing device 13 is composed of a speed reducer and gears. The speed reducer drives the gear set to provide power for the slewing arm 15 to slew. During operation, when the train arrives at the loading station, the dispatcher can select the height of the carriage on the control panel according to the type of carriage (C60, C70, C80, etc.), and the lifting device 16 rises and falls to adapt to the type of carriage. After that, the slewing arm 15 rotates 90° so that the nozzle group 17 hovers above the middle position of the carriage. Automatic spraying is carried out under the control of electrical signals, and the nozzle group 17 will realize automatic spraying in each carriage. When all spraying operations are completed, the slewing arm 15 rotates back and waits for the next operation instruction.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
