Abstract
A connecting plate used on a mast of a rotary drilling rig is characterized in that the connecting plate comprises two connection upper plates and a connection lower plate, and the connection upper plates and the connection lower plate are connected through welding. The connecting plate has a simple structure, is easy to assemble, has relatively-low requirements for manufacturing process and greatly saves the fabrication and manufacturing cost.
Description
Technical field
The utility model relates to the rotary drilling rig that uses in a kind of engineering construction, particularly a kind of terminal pad that is used on the rotary drilling rig mast.
Background technology
Rotary drilling rig is the efficient pore-forming equipment of heavy caliber that uses in a kind of foundation construction, and the drilling rod that its utilization remains vertical direction directly rotates, excavates ground, thereby forms the stake hole of the required diameter and the degree of depth fast on ground.This rotary drilling rig since power big, power is strong, easy to use, pore-forming is quick, so in the foundation construction process of the engineering of being widely used in, building.It is the whole plate machine-shaping of 80mm that terminal pad on the existing rotary drilling rig mast adopts thickness, and its difficult processing is big, technological requirement and manufacturing cost height.
The utility model content
The utility model be to provide a kind of easy to use, be used for terminal pad on the rotary drilling rig mast reliably, to solve shortcoming in the above-mentioned background technology with not enough.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of terminal pad that is used on the rotary drilling rig middle mast is characterized in that, described terminal pad is connected lower wall and is formed by dish in two connections and one, coils in the described connection and is connected lower wall by being welded to connect.
Beneficial effect: the utility model is simple in structure, and assembling is easy, and processing technology requires relatively low, has saved manufacturing, processing cost greatly.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete accompanying drawing, further set forth the utility model:
As shown in Figure 1, a kind of terminal pad that is used on the rotary drilling rig mast described in the utility model comprises in two connections that dish 1 is connected lower wall 2 with one.To adopt thickness be that the steel plate of 80mm processes to dish in two connections, and connecting lower wall, to adopt thickness be that the steel plate addition of 25mm forms.Dish in the connection, connect after the lower wall assembly unit in the welding position 3 and carry out welding forming, carry out integral body again and process.Connecting lower wall 2 was the steel plate that the steel plate of 80mm changes 25mm into by former thickness, had saved raw material greatly, simultaneously, wholely adopted the first assembly unit welding accurately machined technological process in back, had reduced technological requirement and processing cost.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (1)
1. a terminal pad that is used on the rotary drilling rig middle mast is characterized in that, described terminal pad is connected lower wall and is formed by dish in two connections and one, coils in the described connection and is connected lower wall and welds mutually.
