Abstract
The utility model relates to a main control hydraulic valve body sand box of a crawler excavator. The main control hydraulic valve body sand box of the crawler excavator is characterized by comprising a frame-shaped box body which is formed by welding a front steel plate, a rear steel plate, a left steel plate and a right steel plate. The upper end and the lower end of the frame-shaped box body are connected with cover plates of the same structure, the connecting structure of the upper end and the lower end of the frame-shaped box body and the cover plates is that clamping grooves are arranged on the sides of the upper end face and the lower end face of the frame-shaped box body, clamping grooves corresponding to the clamping grooves of the frame-shaped box body are arranged on the cover plates, and the clamping grooves of the frame-shaped box body is connected with the clamping grooves of the cover plates in locking mode through bolts and nuts. The upper end and the lower end of the frame-shaped box body are connected with the cover plates, and main control hydraulic valve body sand box of the crawler excavator guarantees that wall displacement is avoided during casting, prevents casting members from generating shrinkage porosity, and guarantees product quality.
Description
Technical field
The utility model relates to a kind of foundry sand case, particularly a kind of crawler-mounted excavator master control hydraulic valve sandbox.
Background technology
Crawler-mounted excavator master control hydraulic valve is mainly used in large excavator master control hydraulic control system, is the key components and parts of hydraulic circuit control.Because crawler-mounted excavator master control hydraulic valve foundry goods is thick big, be prone to the displacement of generation type wall during cast, cause foundry goods to produce shrinkage cavity shrinkage porosity, influence product quality.
Summary of the invention
The technical problem that the utility model will solve provides a kind of crawler-mounted excavator master control hydraulic valve sandbox of type wall displacement when avoiding pouring into a mould.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of crawler-mounted excavator master control hydraulic valve sandbox; Its innovative point is: comprise by the shaped as frame casing of four block plate welding fabrications all around; The identical cover plate of top and bottom syndeton of said shaped as frame casing; Said shaped as frame casing upper and lower end and cover plate syndeton are: the upper and lower end face side of said shaped as frame casing is provided with draw-in groove, and cover plate is provided with and the corresponding draw-in groove of shaped as frame casing draw-in groove, and the draw-in groove of said shaped as frame casing is connected locking with the draw-in groove of cover plate through bolt, nut.
Further, said shaped as frame casing upper surface is provided with locating hole, has corresponding through hole on the cover plate, and alignment pin passes through hole and stretches in the locating hole.
The advantage of the utility model is: shaped as frame casing upper and lower end connects cover plate, and it can the displacement of generation type wall when guaranteeing to pour into a mould, and avoids foundry goods to produce shrinkage cavity shrinkage porosity, and shadow guarantees product quality.
Description of drawings
Fig. 1 is the utility model crawler-mounted excavator master control hydraulic valve sandbox front view.
Fig. 2 is a shaped as frame casing vertical view in the utility model.
Fig. 3 is the utility model cover plate vertical view.
The specific embodiment
Like Fig. 1,2, shown in 3, comprise by the shaped as frame casing 1 of four block plate welding fabrications all around, the cover plate 2,3 that syndeton is identical in the top and bottom of shaped as frame casing 1, cover plate 2,3 is made up of several reinforcements that laterally arrange of welding on the plate body.
Shaped as frame casing 1 upper and lower end and cover plate 2,3 syndetons are: shaped as frame casing 1 upper and lower end face side is provided with draw-in groove 11; Cover plate 2,3 is provided with the draw-in groove 21 corresponding with shaped as frame casing draw-in groove 11, and the draw-in groove 11 of shaped as frame casing 1 is connected locking with the draw-in groove 21 of cover plate 2,3 through bolt 3, nut 4.In shaped as frame casing 1 upper surface locating hole 5 is set, has corresponding through hole 6, one alignment pins on the cover plate 2 and pass through hole 6 and stretch in the locating hole 5, also have the hole of placing cast gate, rising head on the cover plate 2.
In addition, the sidewall of shaped as frame casing 1 is welded with casing handle 7, is welded with cover plate handle 8 between the reinforcement of cover plate 2.
During concrete the use; Shaped as frame casing 1 and lower surface cover plate are connected fixing through bolt, nut, sand mold is placed in the shaped as frame casing 1 and after burying sand, covers cover plate in shaped as frame casing 1 upper surface; And, through bolt, nut shaped as frame casing 1 and cover plate 2 are locked again with the alignment pin location.
Claims (2)
1. crawler-mounted excavator master control hydraulic valve sandbox; It is characterized in that: comprise by the shaped as frame casing of four block plate welding fabrications all around; The identical cover plate of top and bottom syndeton of said shaped as frame casing; Said shaped as frame casing upper and lower end and cover plate syndeton are: the upper and lower end face side of said shaped as frame casing is provided with draw-in groove, and cover plate is provided with and the corresponding draw-in groove of shaped as frame casing draw-in groove, and the draw-in groove of said shaped as frame casing is connected locking with the draw-in groove of cover plate through bolt, nut.
2. crawler-mounted excavator master control hydraulic valve sandbox according to claim 1 is characterized in that: said shaped as frame casing upper surface is provided with locating hole, has corresponding through hole on the cover plate, and alignment pin passes through hole and stretches in the locating hole.
