Technical field
The present invention relates to engineering machinery field, the firm engineering tower crane of specially a kind of underframe.
Background technology
Tower crane is a kind of crane gear also known as " derrick crane " the most frequently used on construction site, with a section spreading (height) (referred to as " standard knot "), for hanging the raw material of the constructions such as working reinforcing bar, wood stupefied, concrete, steel pipe.Tower crane is work A kind of essential equipment on the ground.Development and national economy, building/real estate height correlation from tower crane industry, therefore, from National economy tendency and real estate industry's development trend see that tower crane industry development has certain scientific meaning.Existing tower crane exists During installation, it is impossible to preferably stablize device, security is not very high, it is possible to can be because bottom installation is inadequate when installing Stablize and cause device to fall down, so as to cause serious casualties and economic loss, greatly improve the dangerous system of device Number.
The content of the invention
It is reasonable in design it is an object of the invention to provide the engineering tower crane that a kind of underframe is consolidated, it is simple in construction, pass through underframe The fixed seat of bottom and the fixing tooth of fixed seat bottom and the fixed plate of underframe both sides are arranged on, be easy to device is preferably solid Live calmly, greatly improve the stability and security of device.
To achieve the above object, the present invention provides following technical scheme:A kind of firm engineering tower crane of underframe, including bottom Frame, tower body, jacking stock, tower top, arm and counter-jib, the underframe upper end are fixedly connected with tower body, the underframe and tower body Between be connected with reinforcement, the tower body and be provided with ladder, the tower body upper end is provided with jacking stock, the jacking stock Upper end is connected with tower top, and the tower top side is connected with arm, and tower top opposite side is connected with counter-jib, and the underframe both sides are fixed Be connected plate, and fixing hole is provided with the fixed plate, and the underframe bottom is provided with fixed seat, the fixed seat bottom connection There is fixing tooth, connecting plate is provided between the fixed seat and underframe, the connecting plate is fixedly connected with fixed seat.
It is preferred that, the underframe is connected with connecting plate by fixing nut.
It is preferred that, it is respectively connected with cable wire between the tower top and arm and counter-jib.
It is preferred that, it is connected with suspension hook on the downside of the arm.
It is preferred that, the suspension hook is made of Al-alloy metal material.
Compared with prior art, beneficial effects of the present invention are as follows:
The present invention is reasonable in design, simple in construction, by the fixed seat of underframe bottom and is arranged on consolidating for fixed seat bottom Fixed tooth and the fixed plate of underframe both sides, are easy to preferably fix device, greatly improve the stability and safety of device Property.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure:1-underframe, 2-tower body, 3-jacking stock, 4-tower top, 5-arm, 6-counter-jib, 7-reinforcement, 8-fixed plate, 9-fixing hole, 10-fixed seat, 11-fixing tooth, 12-connecting plate, 13-cable wire, 14-suspension hook.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, the present invention provides a kind of technical scheme:A kind of firm engineering tower crane of underframe, including underframe 1, tower Body 2, jacking stock 3, tower top 4, arm 5 and counter-jib 6, the upper end of underframe 1 are fixedly connected with tower body 2, the underframe 1 and tower It is connected between body 2 on reinforcement 7, the tower body 2 and is provided with ladder, the upper end of tower body 2 is provided with jacking stock 3, described The upper end of jacking stock 3 is connected with tower top 4, and the side of tower top 4 is connected with arm 5, and the opposite side of tower top 4 is connected with counter-jib 6, institute State the both sides of underframe 1 and be fixedly connected with fixed plate 8, the fixed plate 8 and be provided with fixing hole 9, the bottom of underframe 1 is provided with fixing Seat 10, the bottom of fixed seat 10 is connected with fixing tooth 11, and connecting plate 12 is provided between the fixed seat 10 and underframe 1, described Connecting plate 12 is fixedly connected with fixed seat 10.
