Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mining and smelting, and relates to a maintenance supporting bucket device for a tunnel dump truck. Background Art
[0002] When overhauling tunnel dump trucks, some maintenance items require the bucket to be raised for maintenance. However, relying solely on the lifting cylinder to fix the position of the bucket is not completely reliable. There is a risk of the bucket falling and injuring people after the lifting cylinder is depressurized. Therefore, how to improve the maintenance safety of the tunnel dump truck after the bucket is raised and eliminate the risk of the bucket falling after depressurization after being raised during maintenance is a difficult problem in the safe maintenance process of tunnel dump trucks. Utility Model Content
[0003] The purpose of the utility model is to address the problems existing in the prior art and provide a tunnel dump truck maintenance support bucket device, which solves the problem that the existing tunnel dump truck bucket is raised and there is a risk of pressure relief and falling during the maintenance process, which may harm the personal safety of the operators.
[0004] To this end, the present invention adopts the following technical solutions:
[0005] A tunnel dump truck maintenance support compartment device includes a horizontally arranged lower limit plate, and a first support rod, a second support rod and a third support rod are sequentially provided above the lower limit plate; wherein, the first support rod and the second support rod are vertically connected to the lower limit plate, and the angle between the third support rod and the lower limit plate is 30 to 60 degrees, an upper limit plate is provided above the first support rod, and the two ends of the upper limit plate are fixedly connected to the first support rod and the third support rod respectively, a first cross bar is provided between the first support rod and the second support rod, and a second cross bar is provided between the second support rod and the third support rod.
[0006] Furthermore, the first cross bar and the second cross bar are both arranged horizontally, and are located at the same horizontal position.
[0007] Furthermore, the angle between the upper limit plate and the lower limit plate is 41 degrees.
[0008] Furthermore, the length of the first support rod is smaller than the length of the second support rod.
[0009] Furthermore, the length of the first crossbar is smaller than the length of the second crossbar.
[0010] Furthermore, the length of the first support rod is smaller than the length of the upper limit plate.
[0011] Furthermore, the length of the third support rod is smaller than the length of the lower limit plate.
[0012] The beneficial effects of the present invention are:
[0013] The utility model is used for supporting the bucket of a tunnel dump truck during overhaul to prevent a safety accident caused by pressure release of a bucket lifting cylinder. The utility model has a simple structure and is easy to use, thereby improving the safety factor of the tunnel dump truck during overhaul. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a structural diagram of the utility model;
[0015] Figure 2 It is a side view of the utility model;
[0016] Figure 3 It is a top view of the utility model.
[0017] In the figure, 1-lower limit plate, 2-upper limit plate, 3-first support rod, 4-second support rod, 5-third support rod, 6-first cross bar, 7-second cross bar. DETAILED DESCRIPTION
[0018] The technical solution of the present invention is described below in conjunction with the accompanying drawings and implementation methods.
[0019] like Figure 1 As shown, a tunnel dump truck maintenance support bucket device includes a horizontally arranged lower limit plate 1, and a first support rod 3, a second support rod 4 and a third support rod 5 are arranged above the lower limit plate 1 in sequence; wherein, the first support rod 3 and the second support rod 4 are vertically connected to the lower limit plate 1, and the angle between the third support rod 5 and the lower limit plate 1 is 30 degrees.
[0020] An upper limit plate 2 is provided above the first support rod 3, and both ends of the upper limit plate 2 are fixedly connected to the first support rod 3 and the third support rod 5 respectively. A first cross bar 6 is provided between the first support rod 3 and the second support rod 4, and a second cross bar 7 is provided between the second support rod 4 and the third support rod 5. The first cross bar 6 and the second cross bar 7 are both arranged horizontally and are located at the same horizontal position. In order to enable the device to effectively support the bucket of the tunnel dump truck, ensure absolute support safety, improve support strength, and prevent the first support rod 3, the second support rod 4 and the third support rod 5 from being bent by the bucket, the first cross bar 6 and the second cross bar 7 are provided.
[0021] Specifically, the angle between the upper limit plate 2 and the lower limit plate 1 is 41 degrees. The reason for this setting is that the maximum lifting angle of the bucket of the existing tunnel dump truck is 41°, so the angle between the upper limit plate and the lower limit plate is set to 41°.
[0022] The length of the first support rod 3 is smaller than that of the second support rod 4 , the length of the first cross bar 6 is smaller than that of the second cross bar 7 , the length of the first support rod 3 is smaller than that of the upper limit plate 2 , and the length of the third support rod 5 is smaller than that of the lower limit plate 1 .
[0023] The utility model is used in the following process:
[0024] The repair personnel use two of these devices and place them on the two beams of the vehicle respectively, so that the lower limit plate 1 is stuck on the vehicle beam and the upper limit plate 2 is stuck on the vehicle bucket support beam. After the bucket position is firmly fixed, the repair personnel can carry out maintenance work without the bucket falling, thus ensuring the safety of the maintenance personnel.
