Abstract

The invention provides a box inner cavity size detection system which comprises a body, an execution mechanism and a distance-measuring mechanism, wherein the execution mechanism is arranged at the lower end of the body and is used for driving the body to move; the distance-measuring mechanism is arranged on the body and is used for detecting the size of a box inner cavity, and the distance-measuring mechanism comprises a height distance-measuring sensor arranged at the top of the body. According to the box inner cavity size detection system, detection can be conducted on the box size in the box inner cavity, and inconvenience of detection outside the box on the box size is avoided. After the welding of the box structure is finished, the detection on the size of the box can be started; when a problem is found, the problem can be solved as soon as possible, the repair workload in the later period can be effectively reduced and a large amount of time is saved.

Description

technical field

[0001] The invention relates to the field of construction machinery manufacturing, and more particularly, to a system for detecting the size of a box inner cavity. Background technique

[0002] The existing structural group box is formed, the box body is relatively long, and the requirements for its internal structure size are relatively high, and there are other structural interventions on the outside, it is difficult to inspect the size of the box body from the outside, it is necessary to inspect the inner cavity of the box. Such as figure 1 The outline of the box 10 shown is indicated by a dotted line. This box is located at the lower end of the whole structure, and there are other sub-structures at the upper end and the rear end. However, due to the long box body, manual measurement with a ruler is not easy to achieve and the measurement accuracy cannot be guaranteed. In addition, for the case where the internal dimensions of the box are required to be ...

Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and examples. The left and right directions mentioned in the present invention are based on the actual direction of the reader when facing the document.

[0023] Such as figure 2 and image 3 As shown, the box cavity size detection system according to the present invention includes a main body 50; the actuator is arranged at the lower end of the main body 50 and is used to drive the main body 50 to move; size.

[0024] According to one embodiment of the present invention, the main body 50 is a frame structure (or called a detection trolley) welded by small square tubes. The side plate 52 and the top plate 53 arranged on the side plate 52. The actuator includes a power mechanism and a roller 20 driven by the power mechanism, and the roller 20 is arranged on the bottom plate 51 of the main body 50 . There are preferably 4 rollers 20, so that the running process of the...
