[0001] This utility model relates to the field of concrete injection technology, and more specifically, to a concrete injection device. Background Technology
[0002] In the construction of steel-concrete composite tied arch bridges, the filling of the steel pipe arch ribs is a crucial step. Traditional concrete injection devices often face the problem of potential lumps in the concrete when injecting it into the steel pipe. Although the amount of lumps is not large, the lumps entering the injection chamber and generating heat may clog the injection device during the injection process. Therefore, we have made improvements to address this issue and proposed a new concrete injection device. Utility Model Content

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0029] For an example, please refer to... Figures 1-5 A concrete injection device includes a conveying cylinder 1, a feeding hopper 101 installed on the top of the conveying cylinder 1, a second support frame 107 installed on the top of the feeding hopper 101, and a feeding hopper 102 connected to the second support frame 107. A filter plate 105 is installed inside the feeding hopper 102, and the filter plate 105 is convex in the middle. The filter plate 105 is used to filter lumps in the concrete to prevent lumps from entering the conveying cylinder 1. The filter plate 105 can effectively intercept lumps in the concrete and reduce their entry into the conveying cylinder 1, thereby greatly reducing the occurrence of blockage and improving the smoothness of the injection process. The convex middle of the filter plate 105 increases the area of the filter plate 105 and allows lumps to move to the side of the filter plate 105 to reduce the accumulation of lumps in the middle.
[0030] The filter plate 105 is made of wear-resistant stainless steel. The top surface of the filter plate 105 is composed of multiple inclined surfaces to form a protrusion in the middle of the filter plate 105, and each inclined surface is a straight surface.
[0031] The motor 112 is existing technology, and its specific structure, operating principle and control are common knowledge, so this application will not elaborate further.
[0032] Furthermore, a first limiting frame 103 is fixedly installed at the bottom of the second support frame 107, and the first limiting frame 103 is inserted into the inner wall of the feed hopper 101. The insertion of the first limiting frame 103 into the feed hopper 101 can limit the feeding hopper 102 and improve the stability of the feeding hopper 102.
[0033] Furthermore, a first support frame 104 is fixedly installed inside the feeding hopper 102, and the filter screen plate 105 is placed on top of the first support frame 104, which can support the filter screen plate 105.
[0034] Furthermore, a second limiting frame 106 is fixedly installed at the bottom of the filter plate 105, and the second limiting frame 106 is inserted into the inner wall of the first support frame 104. The second limiting frame 106 can cooperate with the first support frame 104 to limit the filter plate 105, thereby improving the stability of the filter plate 105. The filter plate 105 can be removed from the feeding hopper 102 for easy cleaning and replacement.
[0035] Furthermore, handles 109 are fixedly installed on both sides of the top of the feeding hopper 102, and the handles 109 are designed to facilitate the picking up and putting down of the feeding hopper 102.
[0036] Furthermore, limit rods 108 are fixedly installed on both sides of the bottom of the second support frame 107, and limit grooves 110 are opened on both sides of the feed hopper 101. The limit rods 108 are inserted into the inner wall of the limit grooves 110, and the insertion of the limit rods 108 into the limit grooves 110 can further limit the feed hopper 102.
[0037] Furthermore, an auger 111 is installed inside the conveying cylinder 1. A motor 112 connected to the auger 111 is installed at one end of the conveying cylinder 1. A discharge pipe 113 is connected to the bottom of the conveying cylinder 1. The discharge pipe 113 is used to connect to the pipeline. The motor 112 is used to drive the auger 111 to rotate, so that the concrete is conveyed by the auger 111 and enters the pipeline through the discharge pipe 113 and is injected into the corresponding construction position through the pipeline.
[0038] Furthermore, connecting seats 114 are fixedly installed on both sides of the bottom of the conveying cylinder 1, and a support frame 115 is fixedly connected between the bottoms of the two connecting seats 114. The support frame 115 and the connecting seats 114 cooperate to support the conveying cylinder 1.
[0039] Furthermore, a number of wheels 116 are installed at the bottom of the support frame 115, and a handrail 117 is installed at the top of the support frame 115. The handrail 117 and the wheels 116 work together to facilitate the movement of this application.
[0040] Furthermore, a first support rod 2 is installed on the handrail 117. The first support rod 2 is threadedly connected to a hand-tightening bolt 201. One end of the hand-tightening bolt 201 is connected to an L-shaped pressure plate 202 through a bearing. The L-shaped pressure plate 202 presses against the top of one side of the second support frame 107. A second support rod 203 is fixedly installed on the L-shaped pressure plate 202. One end of the second support rod 203 passes through the first support rod 2. The pressing of the second support frame 107 by the L-shaped pressure plate 202 can fix the position of the feeding hopper 102 and improve the stability of the feeding hopper 102 during use.
[0041] The concrete injection device provided by this utility model is used as follows:
[0042] Concrete is added into the feeding hopper 102, then filtered by the filter screen plate 105 and enters the feeding hopper 101, and then enters the conveying cylinder 1. Under the conveying of the auger 111, the concrete enters the pipeline through the discharge pipe 113 and is injected into the corresponding construction position through the pipeline.
[0043] After use, turn the hand-tightening bolt 201 to drive the L-shaped pressure plate 202 to separate from the second support frame 107. Hold the handle 109 and pull it upward to separate the first limiting frame 103 from the feed hopper 101 to remove the feed hopper 102. Then pour out the clumps filtered out of the feed hopper 102. Use a high-pressure spray gun or other equipment to clean the feed hopper 102, filter plate 105, feed hopper 101, auger 111, and conveyor cylinder 1. After cleaning, insert the first limiting frame 103 into the feed hopper 101, and then turn the hand-tightening bolt 201 to press the L-shaped pressure plate 202 onto the second support frame 107.
