Description

A kind of derrick crane railing
Technical field
The utility model is related to a kind of derrick crane railing, belongs to derrick crane technical field.
Background technology
As depicted in figs. 1 and 2, existing derrick crane railing is filled as a kind of safety for being used to protect personnel's fall arrest Put, it is general that U-shaped bending tube 1, the punching two ends of bending tube 1 are bent into using round steel pipe, and assign into guardrail base 3, then Bending tube 1 is fixedly mounted on guardrail base 3 using split pin 4;It is welded on after the punching of transverse tube 2 on bending tube 1.Meanwhile, it is adjacent Two railings (i.e. the component parts of bending tube 1 and transverse tube 2) between use clamping plate 5 and supporting bolt connection, this railing Complex manufacturing, requirement on machining accuracy is high, installs cumbersome, it has not been convenient to.
The content of the invention
In view of the above-mentioned problems of the prior art, the utility model provides a kind of derrick crane railing, it is produced Technique is simple, and required precision is not high;Without clamping plate connection, easy installation and removal.
To achieve these goals, a kind of derrick crane railing that the utility model is used, including several independences Sub- railing, every sub- railing includes two vertical tubes and several transverse tubes being welded between two vertical tubes, each vertical tube Bottom is detachably arranged on guardrail base.
Preferably, the transverse tube in every sub- railing has two, and a transverse tube is welded between the top of two vertical tubes, Another transverse tube is welded on the middle part of two vertical tubes.
Preferably, the guardrail base is provided with the standpipe for being used for installing vertical tube, and the vertical tube is hollow pipe, vertical tube Bottom is provided with fixing hole, and vertical tube is enclosed on standpipe, and is mounted by means of bolts on guardrail base.
Compared with prior art, the utility model constitutes whole column using multiple independent sub- railings of direct Type of Welding Bar, the bottom of every sub- railing is detachably arranged on guardrail base, and simple production process, required precision is not high;Connected two Connected between individual sub- railing without clamping plate, easy installation and removal.The bottom of sub- railing can be bolted, the technique of guardrail base Simply, it is easy for installation, improve peace and tear convenience and security open.
Brief description of the drawings
Fig. 1 is the structural representation of existing derrick crane railing;
Fig. 2 is the structure for amplifying signal at I in Fig. 1;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is the structure for amplifying signal at I in Fig. 3.
In figure:1st, bending tube, 2, transverse tube, 3, guardrail base, 4, split pin, 5, clamping plate, 6, bolt, 7, vertical tube.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 3 and Figure 4, a kind of derrick crane railing, including several independent sub- railings, every sub- railing Including two vertical tubes 7 and several transverse tubes 2 being welded between two vertical tubes 7, the bottom of each vertical tube 7 is removably installed On guardrail base 3.Wherein, the quantity of transverse tube 2 can be set as needed.
Preferably, the transverse tube 2 in every sub- railing has two, a transverse tube 2 be welded on two vertical tubes 7 top it Between, another transverse tube 2 is welded on the middle part of two vertical tubes 7.
Preferably, the guardrail base 3 is provided with the standpipe for being used for installing vertical tube 7, and the vertical tube 7 is hollow pipe, is erected The bottom of pipe 7 is provided with fixing hole, and vertical tube 7 is enclosed on standpipe, and is fixedly mounted on by bolt 6 on guardrail base 3.
In use, the installation and removal of sub- railing can be realized by demounting bolt 6.Vertical tube structure on guardrail base 3 is simple, Simple production process.Every sub- railing is made up of the vertical tube 7 and transverse tube 2 of welding, than existing U-shaped bending tube, production technology Simply, efficiency high.Connected between two adjacent sub- railings without clamping plate, installing/dismounting is more convenient.
From said structure, the utility model constitutes whole column using the sub- railing of multiple independences of direct Type of Welding Bar, the bottom of every sub- railing is detachably arranged on guardrail base, and simple production process, required precision is not high;Connected two Connected between individual sub- railing without clamping plate, easy installation and removal.The bottom of sub- railing can be bolted, the technique of guardrail base Simply, it is easy for installation, improve peace and tear convenience and security open.
