The hydraulic jacking device comprises a derrick, a standard knot and a hydraulic pump, the standard knot is located in the derrick, the hydraulic jacking device further comprises a first hydraulic cylinder and a second hydraulic cylinder fixedly arranged on two sides of the standard knot, a first movable stopping block matched with a first hydraulic cylinder piston head and a second movable stopping block matched with a second hydraulic cylinder piston head are further arranged on the lateral wall of the derrick, and the first hydraulic cylinder and the second hydraulic cylinder are driven by a hydraulic pump. By adoption of the technical scheme, the hydraulic jacking device has the advantages of reducing energy consumption, saving jacking time of the standard knot, and being strong in lifting capacity, high in erecting height and convenient to install and disassemble.
Description
Technical field
The utility model discloses hydraulic jacking device, belong to the elevator field that the places such as building ground, construction site are used.Especially for the jacking apparatus of double hydraulic cylinder.
Background technology
In high-building construction for making things convenient for improving material that steel headframe must be arranged.Do not have self-hoisting unit of TQ 60/80 for solving traditional steel headframe, lifting is dangerous, the problem that security effectiveness is low, and the derrick with jacking function arises at the historic moment.
Application number having occurred subsequently is 94248578, and the applying date is on December 20th, 1994, and denomination of invention is the patented technology scheme of Mulitfunction high speed wellhead by hydraulic lift.This patented technology scheme is: the derrick body is by four head tree angle steel, the derrick cross bar, the derrick brace consists of, jacking inner sleeve chord position is in the middle of four root post angle steel, the four sides respectively fills four track adjusting wheels up and down, track adjusting wheel is take column angle steel interior angle as guided way, the installation gin pole of jacking inner sleeve top of the trellis is along the installation gin pole of centre of gration rotation, pulley, the rope made of hemp can roll at the installation gin pole, be equipped with on the column of stock in the jacking and use the gin pole supporting base, use gin pole to fix by becoming spoke steel rope and supporting base, stock is divided into lifting body in the jacking, it is characterized in that lifting body adopts hydraulic climbing mechanism, the jacking inner sleeve has been set up, lower platform, a side of stock is provided with the movable bracket that there is hook at two ends in jacking, carriage links to each other with the entablatrance of stock in the jacking by hydraulic cylinder piston, two channel-section steels that bind are arranged at stock top in the jacking, and the channel-section steel that binds links to each other with interior stock, and the both sides, bottom respectively are provided with one the fixing block of pin.Although this patented technology scheme has advantages of that the jacking apparatus resistance to overturning is good, the jacking travelling speed is high, load-carrying ability is strong, antenna height is high, easy installation and removal, safe and reliable to operation, but, because this device has only been used a hydraulic actuating cylinder, therefore, can occur intermittently in the jacking process, and then affect the jacking travelling speed; In addition, the structure relative complex of this device is so that install, dismantle all inconvenient.
?
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of reduction energy consumption that has, and saves the jacking time of standard knot, the jacking apparatus of the advantage that load-carrying ability is strong, antenna height is high, be easy for installation and removal.
For realizing above-mentioned technical purpose, the technical solution of the utility model is:
Hydraulic jacking device, comprise derrick 1, standard knot 2 and Hydraulic Pump 3, described standard knot 2 is positioned at derrick 1, it is characterized in that: also comprise the first hydraulic actuating cylinder 4 and the second hydraulic actuating cylinder 5 that are fixedly installed on standard knot 2 both sides, described derrick 1 sidewall also is provided with and the first active block stop 6 of the first hydraulic actuating cylinder 4 piston heads coupling and the second active block stop 7 that mates with the second hydraulic actuating cylinder 5 piston heads, and described the first hydraulic actuating cylinder 4 and the second hydraulic actuating cylinder 5 are driven by Hydraulic Pump 3.
The top of derrick 1 described in the utility model also is provided with cover frame 8, and described cover frame 8 is movable the connection with derrick 1.
Because the utility model has adopted technique scheme, therefore, has following beneficial effect:
Owing to being provided with the first hydraulic actuating cylinder and the second hydraulic actuating cylinder, therefore, when one of them hydraulic actuating cylinder elongation, another hydraulic actuating cylinder shrinks, and utilizes active block stop corresponding to hydraulic cylinder piston as support, realizes the jacking of standard knot.
Its principle of work is: standard knot is when rising, and one of them hydraulic actuating cylinder is in elongation state, and the piston on another hydraulic actuating cylinder is in contraction state; When the hydraulic actuating cylinder upper piston that is in elongation state reaches the elongation limit, piston on another hydraulic actuating cylinder is in shrinkage limit, at this moment, block blocks the piston on the hydraulic actuating cylinder that is in shrinkage limit, and, this hydraulic actuating cylinder begins elongation, continues to drive standard knot and rises, and another hydraulic actuating cylinder begins to shrink.And so forth, realize the rising of standard knot.
Owing to being provided with the cover frame, therefore, when jack-up system rise and fall during to needs height, it is firm that jacking cover frame is closed connection, and hydraulic actuating cylinder all with after the standard maintenance strained condition can carry out the running state of complete machine.
