Description
Technical field
The utility model relates to a kind of novel pit shaft fixing device.
Background technique
It is a kind of mounting type of submersible axial flow pump that steel pit shaft formula is installed, and the ordinary circumstance well-sinking all is fixed on the concrete foundation by stone bolt.But pit shaft will be placed in the concrete well sometimes, because concrete well is not only dark but also narrow, the operating space is not enough, and the people can not go to the shaft bottom down to install, and can't fix with stone bolt.In view of the foregoing, how to become the problem that person skilled presses for solution at not only dark but also narrow concrete well internal fixation pit shaft.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above in the prior art, and a kind of novel pit shaft fixing device is provided.
The utility model relates to a kind of novel pit shaft fixing device, comprise concrete well, the pit shaft of concrete well inside, it is characterized in that: also comprise connecting plate and several middle fixed blocks that is provided with mounting hole, described connecting plate is become with the connection strap place that is connected two steel plates by two steel plates that are parallel to each other, on first steel plate, have laterally zygomorphic U-shaped through hole, on second steel plate, have laterally zygomorphic U-shaped through hole, it circumferentially evenly is provided with some places fixed block in pit shaft outer wall upper edge, every place is two, the centre distance of this two fixed block equals the centre distance of the first steel plate U-shaped through hole, first steel plate is fixed on the fixed block corresponding on the pit shaft by the U-shaped through hole that bolt passes on it, and the U-shaped through hole that second steel plate passes on it by EXPANSION ANCHOR BOLTS is fixed on the concrete well.
Described connection strap is a channel-section steel.
There are 3 places at described fixed block place.
Two fixed blocks in every place fixed block are arranged above and below along the length direction of pit shaft.
The U-shaped through hole of described first steel plate is that laterally the U-shaped through hole of second steel plate is vertical.
The utility model has the advantages that simple in structurely, solve and to descend the shaft bottom to go the problem of installing inadequately, be convenient to installation because of the operating space.

Embodiment
Among the figure, a kind of novel pit shaft fixing device, comprise concrete well 2, the pit shaft 1 of concrete well 2 inside, it is characterized in that: also comprise connecting plate 10 and cylindrical fixed block 21, be processed with tapped hole 22 in the centre of fixed block 21, described connecting plate is by two steel plates that are parallel to each other 12,13 be connected two steel plates 12,13 connection strap 11 is welded, on first steel plate 13, have laterally zygomorphic U-shaped through hole 130, on second steel plate 12, have laterally zygomorphic U-shaped through hole 120, it circumferentially evenly is provided with some places fixed block 21 in pit shaft 1 outer wall upper edge, every place is two, the centre distance of this two fixed block 21 equals the centre distance of the first steel plate 13U shape through hole, first steel plate 13 is fixed on the fixed block 21 corresponding on the pit shaft 1 by the U-shaped through hole 130 that bolt passes on it, and the U-shaped through hole 120 that second steel plate 12 passes on it by EXPANSION ANCHOR BOLTS is fixed on the concrete well 2.
Described connection strap 11 is a channel-section steel.
Two fixed blocks in every place fixed block are arranged above and below along the length direction of pit shaft.
The U-shaped through hole of described first steel plate is that laterally the U-shaped through hole of second steel plate is vertical.
During use, pit shaft is placed on the base foundation of concrete well, submersible axial flow pump is placed in the pit shaft, two EXPANSION ANCHOR BOLTS up and down are housed on concrete walling, EXPANSION ANCHOR BOLTS is passed the vertical U-shaped through hole on the steel plate of connecting plate and connecting plate is fixed on the concrete walling, pass the horizontal U-shaped through hole on first steel plate of connecting plate with bolt and bolt is spun in the tapped hole of fixed block, connecting plate is fastened on the pit shaft.Because the pit shaft outer wall is welded with 3 place's fixed blocks, 3 place's EXPANSION ANCHOR BOLTS also are housed on the concrete walling, respectively pit shaft and concrete well are linked together with 3 connecting plates, like this pit shaft can not rock in any one direction, thereby has played fixing effect.Since EXPANSION ANCHOR BOLTS when being contained on the concrete walling can not with fixed block on the pit shaft on same center line, so the vertical U-shaped through hole on the connecting plate and laterally the U-shaped through hole can regulate the deviation of vertical direction and substantially horizontal respectively, be convenient to install.
Below only expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
The utility model has the advantages that simple in structurely, solve and to descend the shaft bottom to go the problem of installing not enough because of the operating space, be convenient to installation.
