At present, tower crane is a kind of crane gear the most frequently used on construction site, also known as derrick crane, for slinging steel
The construction raw material such as muscle, wood stupefied, concrete, steel pipe, tower crane are a kind of essential equipment on construction site.At present
Tower crane after built completion, lack the device of controllable tower crane height, when the material that needs a person with the qualifications of a general is transported to and tower crane height phase
During near place, unnecessary trouble can be caused, influences the operating efficiency of tower crane, or even cause the damage of tower crane device, existed
Potential safety hazard.
The content of the invention
The present invention is to overcome in the prior art, and tower crane and influences tower crane due to a lack of the device of controllable tower crane height
Operating efficiency, or even cause the damage of tower crane device, the problem of potential safety hazard be present, there is provided one kind can be entered to tower crane height
The liftable tower crane of row regulation.
To achieve the above object, the present invention uses following technical scheme：
A kind of liftable tower crane, including support frame, the control room on support frame, the height regulation dress in support frame
Put, the crane arm on support frame side, the counter-jib on support frame opposite side, the mass on counter-jib and
Suspension hook on crane arm；Suspension hook is slidably connected with crane arm.
In the present invention, support frame is used to be supported whole tower crane, and arrangement for adjusting height is used to enter tower crane support frame
The lifting of row height, control room ensure tower crane energy normal operation.The present invention has the characteristics of tower crane height can be adjusted.
Preferably, arrangement for adjusting height includes sealed cabinet, the containment vessel in sealed cabinet, if in containment vessel
Dry copper cash, adapter sleeve, upper push-rod and lower push-rod in adapter sleeve, the push pedal on upper push-rod；Lower push-rod and protection
Shell is fixedly connected, and each copper cash is in spring form.When copper cash expanded by heating, under the promotion of upper push-rod and lower push-rod, Neng Gouti
The height of high tower crane support frame；And when copper cash contract on cooling, it just can reduce the height of reduction tower crane support frame.
Preferably, heater and cooler are additionally provided with containment vessel.Heater and cooler are used in containment vessel
Copper cash is heated and cooled down, and heater and cooler can be remotely controlled operation by operating personnel in control room.
Preferably, be additionally provided with balance arm brace between support frame and counter-jib, balance arm brace respectively with support frame and
Counter-jib is fixedly connected.Balance arm brace is used to strengthen fixation of the counter-jib on support frame.
Preferably, be additionally provided with lifting arm brace between support frame and crane arm, lifting arm brace respectively with support frame and
Crane arm is fixedly connected, and clamping plate is additionally provided with lifting arm brace, and clamping plate is fixedly connected with lifting arm brace.Lifting arm brace is same
For strengthening fixation of the crane arm on support frame.
Therefore, the present invention has the advantages that：By the way that the copper cash in arrangement for adjusting height is heated or cooled,
So as to reach the purpose that the height of tower crane support frame is adjusted.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present invention；
Fig. 2 is a kind of structural representation of the arrangement for adjusting height in the present invention.
In figure：Support frame 1, control room 2, arrangement for adjusting height 3, crane arm 4, counter-jib 5, mass 6, suspension hook 7, sealing
Cabinet 8, containment vessel 9, copper cash 10, adapter sleeve 11, upper push-rod 12, lower push-rod 13, push pedal 14, balance arm brace 15, lifting arm brace
16th, clamping plate 17.
Embodiment
The present invention will be further described with embodiment below in conjunction with the accompanying drawings：
A kind of liftable tower crane as shown in Figure 1, including support frame 1, the control room 2 on support frame, in support frame
Arrangement for adjusting height 3, the crane arm 4 on support frame side, the counter-jib 5 on support frame opposite side, located at flat
Weigh the mass 6 on arm and the suspension hook 7 on crane arm；Suspension hook is slidably connected with crane arm.
As shown in Fig. 2 arrangement for adjusting height includes sealed cabinet 8, the containment vessel 9 in sealed cabinet, in containment vessel
Several copper cash 10, adapter sleeve 11, upper push-rod 12 and lower push-rod 13 in adapter sleeve, the push pedal on upper push-rod
14；Lower push-rod is fixedly connected with containment vessel, and each copper cash is in spring form.When copper cash expanded by heating, in upper push-rod and lower push-rod
Promotion under, it is possible to increase the height of tower crane support frame；And when copper cash contract on cooling, it just can reduce and reduce tower crane support
The height of frame.In addition, heater and cooler are additionally provided with containment vessel.Heater and cooler are used for the copper cash in containment vessel
Heated and cooled down, heater and cooler can be remotely controlled operation by operating personnel in control room.
Be additionally provided between the support frame and counter-jib of liftable tower crane balance arm brace 15, balance arm brace respectively with support
Frame is fixedly connected with counter-jib.Balance arm brace is used to strengthen fixation of the counter-jib on support frame.Support frame and crane arm it
Between be additionally provided with lifting arm brace 16, lifting arm brace is fixedly connected with support frame and crane arm respectively, is also set on lifting arm brace
There is clamping plate 17, clamping plate is fixedly connected with lifting arm brace.Lifting arm brace is equally used for strengthening crane arm consolidating on support frame
It is fixed.
The application method and principle of the present invention is as follows：
When needing to improve the height of tower crane support frame, operating personnel start heater start-up operation in control room, make copper cash
