Technical field
The utility model relates to a kind of derrick, the bolted sheave wheel platform of especially a kind of L type.
Background technology
In the tradition derrick, the headgear pulley beam all is to adopt U-bolt to connect with being connected of sheave wheel platform beam.Fig. 3 is the connection diagram of prior art headgear pulley beam and sheave wheel platform beam, as shown in Figure 3: because sheave wheel platform beam 2 higher (the V-type derrick has 1.35 meters), be again work high above the ground, use U-bolt 7 to install not only inconvenience but also dangerous, time-consuming taking a lot of work.Because people's prefix G-7 beam is all arranged at the middle part of sheave wheel platform beam 2, use U-bolt 7 that headgear pulley beam 1 difficulty is installed in this position very big, brings very big inconvenience for constructor's operation.
The utility model content
The purpose of this utility model provides the bolted sheave wheel platform of a kind of L type, effectively solves existing headgear pulley beam and is connected inconvenient, dangerous, time-consuming defective such as take a lot of work with the sheave wheel platform beam.
To achieve these goals, the utility model provides a kind of L type bolted sheave wheel platform, comprises headgear pulley beam and sheave wheel platform beam, and described headgear pulley beam is connected by the array L type bolt that is oppositely arranged with the sheave wheel platform beam.
Described L type bolt is made up of superposed straight screw rod and the arc screw rod that is positioned at the bottom, and described straight screw rod is connected with described headgear pulley beam, and described arc screw rod is connected with described sheave wheel platform beam.
Described sheave wheel platform beam is provided with pole, and described arc screw rod is connected with described sheave wheel platform beam by catching on described pole.
Described pole is positioned at the both sides of described sheave wheel platform beam, and the pole outer rim is alignd with the limit portion of described sheave wheel platform beam.
Offer connecting hole on the described headgear pulley beam, an end of described straight screw rod passes described connecting hole and is fastened on the described headgear pulley beam by nut.
The diameter of described pole is 30mm～50mm.
The diameter of described pole is 40mm.
The length of described pole is 150mm～250mm.
The length of described pole is 200mm.
The utility model proposes the bolted sheave wheel platform of a kind of L type, effectively solve existing headgear pulley beam and be connected inconvenient, dangerous, time-consuming defective such as take a lot of work with the sheave wheel platform beam.The utility model adopts L type bolt to connect headgear pulley beam and sheave wheel platform beam, installs and safe and convenient to use, time saving and energy saving and saving cost.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the bolted sheave wheel platform structure chart of the utility model L type;
