Description

Technical Field

[0001] This utility model belongs to the field of urban municipal engineering construction technology, specifically relating to a mobile, same-condition maintenance vehicle. Background Technology

[0002] In the process of urban construction and development, considering the large area of ​​the main structure and the large volume of concrete poured on site, in order to meet the needs of placing concrete test blocks under the same conditions on site during construction, conventional test block curing under the same conditions accounts for a large part of the test block curing, such as demolding test blocks and 600℃ age test blocks. Due to the large number of test blocks under the same conditions, the management is not standardized and test blocks are easily lost.

[0003] Therefore, test block curing vehicles have emerged. Existing test block curing vehicles, such as the tool for protecting test blocks cured under the same conditions (application number 202021004631.8), have a left-side railing, a right-side railing to the right of the left-side railing, a top railing at the top of the left and right railings, front and rear railings at the front and rear of the left and right railings, and a bottom railing at the bottom of the left and right railings. The intersections of the left, front, rear, and bottom railings, as well as the intersections of the right, front, rear, and bottom railings, are fixedly connected by node connecting blocks. Universal casters are fixedly installed at the bottom of the node connecting blocks. The right side of the top railing is movably connected to the right railing via two rotating mechanisms, and the left side of the top railing is fixedly connected to the left railing via two locking mechanisms. Three placement plates are placed on top of the bottom railing between the left and right railings. While this device can achieve the movement and transportation of test blocks under the same conditions, it still has the following shortcomings:

[0004] 1. The device cannot be fixed in a specific position to remove the test block, which means that one person must hold the device while the other person removes the test block, making it inconvenient to use.

[0005] 2. When taking out the test block, you need to lift it upwards, and when putting it in, you also need to lift it up first, which is time-consuming and laborious.

[0006] 3. The device can only be pushed by hand along the fence. Most tools are usually set low, requiring bending over to push them, which is inconvenient. Utility Model Content

[0007] To address the problems existing in the prior art, a mobile, same-condition maintenance vehicle is proposed.

[0029] Example 1:

[0030] Please see Figure 1-Figure 2 To address the issue of the inconvenience of moving the test block curing vehicle, this technical solution proposes a mobile, same-condition curing vehicle, comprising a square tube frame 6, with three layers of test block placement plates 14 connected to the side wall of the square tube frame 6, and a door 8 rotatably connected to one side of the square tube frame 6; in this embodiment, the door 8 is a double-opening door, with locking latches 13 connected to each door 8, and a nameplate 10 and a smart digital display screen 9 connected to the door 8. A column 15 is connected to the bottom of the square tube frame 6, and a moving component 7 is provided on the column 15; a push rod is provided at the top of the square tube frame 6.

[0031] The push rod in this embodiment includes an inner push rod 2 and an outer push rod 1. The inner push rod 2 is fixed to the top of the square tube frame 6. The outer push rod 1 can slide along the rod axis outside the inner push rod 2. Positioning holes 4 are opened on the side walls of both the inner push rod 2 and the outer push rod 1. The height adjustment pin 5 passes through the positioning holes 4 on the inner push rod 2 and the outer push rod 1 respectively to fix the outer push rod 1. The top of the outer push rod 1 is connected to a handle 3.

[0032] To facilitate the handling of test blocks, three sets of sliding grooves 11 are vertically opened on the two side walls of the square tube frame 6 in this embodiment, and the two sides of the test block placement plate 14 can slide within the sliding grooves 11.

[0033] Example 2:

[0034] The rest is the same as in Embodiment 1, except that: to solve the technical problem of conveniently fixing and placing test blocks on the maintenance vehicle, this embodiment has four sets of columns 15, which are respectively connected to the four corners of the bottom of the square tube frame 6. This embodiment has two sets of movable components 7, respectively located between the two columns 15 on both sides, including a first support plate 71 and a second support plate 710. One end of the first support plate 71 is located at the bottom of one end of the second support plate 710, and the other end of the first support plate 71 is hinged to the column 15; the bottom of the other end of the second support plate 710 is connected to a pad 79, the bottom of the pad 79 is flush with the bottom of the first support plate 71, and this end of the second support plate 710 is hinged to the opposite column 15 on the same side. In this embodiment, both the first support plate 71 and the second support plate 710 are hinged to the column 15 using hinges 72; the second support plate 710... A limiting rod 76 is rotatably connected to the side of the support plate 710, and a locking block 74 is connected to the bottom of the limiting rod 76. A fixing block 78 is also connected to the side of the second support plate 710. One end of a return spring 77 is connected to the fixing block 78, and the other end of the return spring 77 is connected to the side wall of the limiting rod 76 and can drive the limiting rod 76 to rotate. A limiting block 75 is connected to the bottom of the first connecting plate corresponding to the limiting rod 76. The movement of the limiting rod 76 toward the first support plate 71 can cause the locking block 74 to lock under the limiting block 75. A caster wheel 73 is connected to the bottom of the side of the first support plate 71 closest to the column 15, and a caster wheel 73 is connected to the bottom of the pad 79. The top of the first support plate 71 is flush with the bottom of the second support plate 710, and the bottom of the first support plate 71 is flush with the bottom of the pad 79.

[0035] To enable the movable components 7 on both sides to retract and extend synchronously, the two first support plates 71 of the movable components 7 on both sides are connected by a first connecting rod 16; the two second support plates 710 of the movable components 7 on both sides are connected by a second connecting rod 17; and the two limiting rods 76 of the movable components 7 on both sides are connected by a third connecting rod 18. In this way, only stepping on one side of the movable component 7 is required to achieve synchronous retraction and extension of the movable components 7 on both sides.

[0036] Working principle:

[0037] Stepping on the second support rod causes the second and first support rods to move downwards. At this time, the locking block 74 on the limiting rod 76 engages with the lower part of the limiting block 75, and the first and second support rods are fixed. The caster wheel 73 extends out of the column 15. At this time, adjust the length of the push rod and push the push rod to move the maintenance vehicle. After reaching the destination, manually pry the limiting rod 76 to disengage the locking block 74 from the limiting block 75. The first and second support rods separate, and the caster wheel 73 retracts. At this time, the column 15 supports the ground. Open the lock on the latch 13, open the door 8, pull out the placement plate 14, and take out the test block.

[0038] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
