Description
Technical Field
The invention relates to the field of solid propellant charging, in particular to a rainproof shed of a push-pull type mixing pot transfer trolley with a guide rail.
Background
The production of solid rocket propellants is divided into a continuous production mode and an intermittent production mode, and most propellants adopt the intermittent production mode due to the limitation of production process conditions. Therefore, the storage and the transportation of the propellant slurry raw materials are carried out by adopting the mixing pot during the production, the propellant charging process has great danger, certain safe distance is ensured among all workshops, the transportation of the mixing pot is completed by the mixing pot transportation vehicle, and most of the transportation is carried out in the open air environment. Moisture has a significant impact on the performance of the propellant, so that rain protection is of paramount importance. The rainproof measure of the mixing pot used in the prior production is to utilize an independent rainproof cloth to prevent rain, and people need to climb onto a transport vehicle and step on an arc-shaped frame to ascend for covering (the pedal area is only 200 cm)2) And the phenomenon of slipping and falling easily occurs in wet and slippery rainy days, so that operating personnel are injured, and the potential safety hazard is formed. The link of covering the waterproof cloth occupies time of 5-10 minutes for operating personnel, and during the production feeding period, the mixing pot is circulated among four production processes, namely the four processes need to take and unload the waterproof cloth, so that the work of taking and unloading the waterproof cloth is time-consuming and labor-consuming, and the personnel operation is inconvenient. In addition, as the waterproof cloth is not easy to be fixed on the mixing pot, the waterproof cloth is easy to open and drop in the transportation process, and the waterproof cloth is easy to be scratched in the cover-covering process to cause rainwater to enter the propellant slurry to influence the performance of the propellant slurry. Along with the increase of the loading quantity year by year, the production task is heavier and heavier, the high-efficiency safety of equipment and facilities is ensured, the high-efficiency safety becomes the main direction of the safety work of a factory, and people caused by unsafe factors of the equipment and facilities exist according to statisticsCasualty events occur frequently, and therefore, the modification of the facility not only necessitates the need for safe production but also reduces unnecessary economic losses. Therefore, there is a need for a mixing pot transfer car rain shelter that is easy to operate.
Push-pull type weather enclosure among the prior art all adopts and adds a leading wheel on the weather enclosure stand to realize the removal and the flexible of weather enclosure. The rain-proof shed can not resist the influence caused by wind and is not convenient to be fixed on the transfer trolley.
Disclosure of Invention
In order to overcome the defects that the movable type rain-proof shed can not be fixed on a transfer trolley and can not try to effectively shield a mixing pot in windy conditions in the prior art, the invention provides the push-pull type mixing pot transfer trolley rain-proof shed with the guide rail.
The invention comprises two linear guide rails, a plurality of sliding blocks and a plurality of main frames; the two linear guide rails are symmetrically distributed on the upper surface of the body of the mixing pot transfer trolley. The main frames are all in a shape of a Chinese character 'men'; the lower ends of the upright columns on the two sides of the main frame are respectively placed on the linear guide rails through the sliding blocks. The upright posts are connected through a hinge frame. The distance between each main frame is 400-600 mm. The waterproof cloth covers the waterproof cloth supporting frames at the top ends of the main frames 4.
The two ends of the straight rod in each waterproof cloth support frame are fixedly connected with the top ends of the two stand columns of the main frame, and the two ends of the arc-shaped rod in each waterproof cloth support frame are fixedly connected with the top ends of the two stand columns of the main frame.
The length of the linear guide rail is the same as that of the vehicle body of the mixing pot transfer vehicle. The linear guide rail is divided into a main rail and a supporting plate according to functions; the cross section of the main track is circular, and the main track is fixed on the upper surface of the supporting plate through a bracket. The surfaces at the 12 o ' clock position, the 3 o ' clock position and the 9 o ' clock position of the outer circumference of the main track are respectively provided with a ball slideway extending along the axial length of the main track. And screw holes connected with the body of the mixing pot transfer trolley are distributed on the supporting plate. The cross section of each ball slideway is in a semicircular arc shape, and the radius of each ball slideway is 1mm smaller than that of the sliding ball.
The sliding block is a shell with an outer square and an inner circle. The surfaces of the 12 o ' clock position, the 3 o ' clock position and the 9 o ' clock position of the inner cavity of the slide block are respectively provided with ball grooves, and sliding balls are respectively embedded in the ball grooves. The lower surface of the sliding block shell is provided with an opening, and the width of the opening is slightly larger than that of the linear guide rail bracket, so that the sliding block can be conveniently installed and slide. And a screw hole for mounting a locking rod is formed in the shell on one side of each sliding block. The top surfaces of the sliding balls embedded in the ball grooves are 1.5-2 mm higher than the surface of the inner cavity of the sliding block respectively
The rainproof device solves the problem of time consumption in the process of covering the waterproof cloth of the mixing pot, avoids potential safety hazards in the process of covering the waterproof cloth, achieves the purpose of rainproof the mixing pot, is suitable for rainproof of various mixing pots in the field of propellant charging of solid rocket engines, and can be popularized in the relevant fields of rainproof in the process of transporting solid rocket engines and the like.
Through actual comparison, the original mixing pot rainproof method and the method of the invention are compared as follows: at present, the time of 6min is consumed for covering the waterproof cloth for the mixed pot transport vehicle in our factory (2 layers of waterproof cloth are covered), the time of 6min is also required for unloading, so that the time of 12min is consumed for loading and unloading the waterproof cloth in one process of charging 1 pot of materials in the whole process, and if 3 pots of materials are charged, the time of 144min is totally calculated according to the processes of weighing, mixing, pouring and cleaning, namely 12 x 3 x 4 x 144. After the push-pull type mixing pot transfer trolley rain-proof shed with the guide rails is used, the time for covering the rain-proof cloth is saved, potential safety hazards are reduced, the problem that rainwater enters propellant slurry to influence the performance of the rain-proof cloth due to the fact that the rain-proof cloth is easy to open and drop in the transportation process and the rain-proof cloth is easy to scratch in the covering process is solved, and the covering efficiency is preliminarily estimated to be improved by more than 80%. The time for loading and unloading the waterproof cloth is saved by 10min according to the procedure of charging 1 pot of materials, and the four procedures are saved by 130 min in total. From the economic point of view, the long-term use of the rain-proof shed of the push-pull type mixing pot transfer trolley with the guide rail is completely necessary.
