Abstract
The utility model discloses an upper supporting base of a tower crane. The upper supporting base comprises a box-shaped supporting bracket and guardrails which are arranged above the box-shaped supporting bracket; the upper supporting base of the tower crane is characterized in that a transverse pin roll for connecting a cargo arm and a balance arm is arranged on a top end surface of the box-shaped supporting bracket; a rib plate and a supporting long rod are welded between the box-shaped supporting bracket and the guardrails; and the guardrails are formed by connecting n-shaped metal frameworks through a transverse connecting pin. The upper supporting base of the tower crane has the beneficial effects that the upper supporting base, the cargo arm and the balance arm are connected by the transverse pin roll rather than the original vertical high-strength bolt pair, so that not only is the installation enabled to be simpler, but also the pin roll direction only needs to be enabled to be fixed and reliable, thereby greatly reducing later checking and maintaining workload, and achieving convenience in use; the stability of the upper supporting base is effectively ensured by the rib plate and the supporting long rod; and the guardrails are formed by connecting a plurality of n-shaped metal frameworks through the transverse connecting pin, so that the upper supporting base is convenient for transporting and dismounting, and especially convenient for work high above the ground.
Description
Technical field
The utility model relates to a kind of tower machine upper bracket, belongs to hoisting crane and manufactures 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, by vertical high strength bolt pair 101, realizes.Use vertical high strength bolt pair to be connected, 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.
As can be seen here, 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.
The utility model content
For solving the deficiencies in the prior art, the purpose of this utility model 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 utility model adopts following technical scheme:
A kind of tower machine upper bracket, comprise: the box-shaped frame support bracket that is set in the tower body 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 connecting the horizontal bearing pin of crane arm, equilibrium arm.
Aforesaid tower machine upper bracket, is characterized in that, between a side of aforementioned box-shaped frame support bracket and guardrail, is welded with gusset.
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 guardrail.
Aforesaid tower machine upper bracket is characterized in that aforementioned guardrail consists of the metal framework of the some n of being fonts.
Aforesaid tower machine upper bracket, is characterized in that, between aforementioned two adjacent metal frameworks, by horizontal connecting pin, connected.
Aforesaid tower machine upper bracket is characterized in that the middle part of aforementioned metal framework is welded with crossbeam.
Usefulness of the present utility model 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 make installation simpler, and only need to guarantee that the bearing pin direction is fixing reliably gets 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 facilitate aloft work.
The accompanying drawing explanation
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 utility model.
The implication of Reference numeral in 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 utility model is done to concrete introduction.
With reference to Fig. 2, tower machine upper bracket of the present utility model, comprise: be set in the box-shaped frame support bracket 201 of tower body (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 for connecting crane arm (not shown), equilibrium arm (not shown), it has replaced original vertical high strength bolt pair, not only make installation simpler, and only need to guarantee that bearing pin 203 directions are fixing reliably gets 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 guardrail 202, 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 guardrail 202 and support stock 205, for guaranteeing the steadiness of this side rail.The guardrail length of this side is relatively long, therefore use the longer support stock of length.
In the utility model, guardrail 202 is that the metal framework 206 by the some n of being fonts forms.
As a kind of preferred scheme, between two adjacent metal frameworks 206, by horizontal connecting pin 207, connected, greatly facilitate carrying and dismounting, especially facilitated 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.
It should be noted that, above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
