Abstract
The invention discloses an upper supporting seat of a tower crane. The upper supporting seat of the tower crane comprises a box-shaped supporting bracket and a fence arranged above the box-shaped supporting bracket, and is characterized in that a transverse pin shaft for connecting a boom with a balance arm is arranged on the top end face of the box-shaped supporting bracket, and rib plates and long supporting rods are arranged between the box-shaped supporting bracket and the fence in a welding way; and the fence is formed by connecting n-shaped metal frames through transverse connecting pins. The upper supporting seat provided by the invention has the advantages that the transverse pin shafts for connecting the upper supporting seat with the boom and the balance arm replace the original vertical high-strength bolt pairs, so that the installation is simpler, and only the fixed and reliable pin shaft direction needs to be ensured, and thus the late inspection and maintenance workload is greatly reduced, and the use is extremely convenient; the rib plates and the long supporting rods effectively guarantee the stability of the upper supporting seat; and the fence is formed by connecting the n-shaped metal frames through the transverse connecting pins, so that the transport, disassembly and assembly are convenient, especially the aerial work is convenient.
Description
Technical field
The present invention relates to a kind of tower machine upper bracket, belong to hoisting crane and make the field.
Background technology
Tower machine upper bracket is used for the pivoting support rotation, and by connecting crane arm and equilibrium arm, keeps the balance of tower machine.
Existing tower machine upper bracket, with reference to Fig. 1, it is connected with crane arm, equilibrium arm, realizes by vertical high strength bolt pair 101.Use vertical high strength bolt pair to connect, not only need to reach the predetermincd tension of regulation, and also need the fastening situation of cyclic check bolt pair in the use procedure of tower machine.
This shows, use existing tower machine upper bracket, comparatively effort not only is installed, and the work capacity of the inspection in later stage, maintenance is larger.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of install simple, the time saving and energy saving tower machine upper bracket of maintenance and inspection.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of tower machine upper bracket, comprise: the box-shaped frame support bracket that is set in the body of the tower upper end, be arranged on the guardrail of aforementioned box-shaped frame support bracket top, it is characterized in that, the top end face of aforementioned box-shaped frame support bracket is provided with for the horizontal bearing pin that connects crane arm, equilibrium arm.
Aforesaid tower machine upper bracket is characterized in that, is welded with gusset between a side of aforementioned box-shaped frame support bracket and the guardrail.
Aforesaid tower machine upper bracket is characterized in that, is welded with the support stock between the opposite side of aforementioned box-shaped frame support bracket and the guardrail.
Aforesaid tower machine upper bracket is characterized in that aforementioned guardrail is made of the metal framework of the some n of being fonts.
Aforesaid tower machine upper bracket is characterized in that, connects by horizontal connecting pin between aforementioned two adjacent metal frameworks.
Aforesaid tower machine upper bracket is characterized in that the middle part of aforementioned metal framework is welded with crossbeam.
Usefulness of the present invention is: upper bracket is connected by horizontal bearing pin with crane arm, equilibrium arm, having replaced the original vertical high strength bolt pair of passing through connects, not only so that install simpler, and only need guarantee that the bearing pin direction is fixing and reliably get final product, greatly reduced the inspection in later stage, the work capacity of maintenance, extremely easy to use; Gusset and support stock have effectively guaranteed the steadiness of upper bracket; Guardrail is connected and composed by horizontal connecting pin by the metal framework of the some n of being fonts, and convenient carrying and dismounting especially make things convenient for aloft work.
Description of drawings
Fig. 1 is the structural representation of existing tower machine upper bracket;
Fig. 2 is the structural representation of a specific embodiment of tower machine upper bracket of the present invention.
The implication of Reference numeral among the figure: the 101-bolt pair, 201-box-shaped frame support bracket, the 202-guardrail, the 203-bearing pin, the 204-gusset, 205-supports stock, 206-metal framework, 207-connecting pin, 208-crossbeam.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
With reference to Fig. 2, tower machine upper bracket of the present invention, comprise: be set in the box-shaped frame support bracket 201 of body of the tower (not shown) upper end, be arranged on the guardrail 202 of box-shaped frame support bracket 201 tops, and the horizontal bearing pin 203 that is arranged on the top end face of box-shaped frame support bracket 201.Horizontal bearing pin 203 is used for connecting crane arm (not shown), equilibrium arm (not shown), it is secondary that it has replaced original vertical high strength bolt, not only so that install simpler, and only need guarantee that bearing pin 203 directions are fixing and reliably get final product, greatly reduced the inspection in later stage, the work capacity of maintenance, extremely easy to use.
As a kind of preferred scheme, be welded with gusset 204 between a side of box-shaped frame support bracket 201 and the guardrail 202, be used for guaranteeing the steadiness of this side rail.The guardrail length of this side is relatively short, therefore use the less gusset 204 of length.
More preferably, be welded with between the opposite side of box-shaped frame support bracket 201 and the guardrail 202 and support stock 205, be used for guaranteeing the steadiness of this side rail.The guardrail length of this side is relatively long, therefore use the long support stock of length.
In the present invention, guardrail 202 is that metal framework 206 by the some n of being fonts consists of.
As a kind of preferred scheme, connect by horizontal connecting pin 207 between two adjacent metal frameworks 206, greatly facilitate carrying and dismounting, especially made things convenient for aloft work.
More preferably, the middle part of metal framework 206 is welded with crossbeam 208, has both guaranteed the intensity of guardrail, has guaranteed again the safety of using.
Need to prove, above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
