Abstract
Description
Technical Field
[0001] This utility model belongs to the field of engineering quality testing technology, and in particular relates to a core-taking clamp for municipal engineering quality testing. Background Technology
[0002] In municipal engineering quality inspection, core sampling is crucial. Accurately obtaining high-quality core samples plays a key role in judging the quality of engineering structures. Traditional core sampling clamps have many problems. For example, they are difficult to hold core samples firmly under complex geological conditions, resulting in easily damaged and poorly intact core samples, which affects the accuracy of the inspection. At the same time, their operation is cumbersome, the inspection efficiency is low, and a lot of manpower and time costs are consumed. Moreover, the existing core sampling clamps are not adaptable enough and cannot be flexibly adjusted for core samples of different sizes and materials, which cannot meet the diverse inspection needs of municipal engineering. There is an urgent need to develop a new type of high-efficiency, stable and highly adaptable core sampling clamp for municipal engineering quality inspection.
[0003] However, the existing core clamps for municipal engineering quality testing are not convenient for effectively holding samples during use. Samples are easy to fall off the device, making it difficult to remove them from the sampling area, thus delaying the sampling work and affecting the progress of subsequent testing. Utility Model Content
[0004] The purpose of this utility model is to provide a core-sampling clamp specifically for municipal engineering quality testing. By setting up a clamping mechanism, it solves the problem that existing core-sampling clamps for municipal engineering quality testing are not convenient for effectively clamping samples during use, and the samples are easy to fall off the device, making it difficult to remove the samples from the sampling area, thus delaying the sampling work and affecting the progress of subsequent testing.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a core sampling clamp for quality testing of municipal engineering projects, including a support block, on which a clamping mechanism and an anti-reverse mechanism are provided;
[0007] The clamping mechanism includes two slots 1 formed at the bottom of the support block, and a slot 2 formed inside the support block. The slot 2 is connected to the two slots 1. A rotating shaft is rotatably connected to the inner wall of the support block. The top of the rotating shaft extends outside the support block, and the bottom of the rotating shaft extends into the slot 2. The anti-reverse mechanism includes a connecting block 1 fixedly connected to the top of the support block. A ratchet gear is fixedly connected to the outer wall of the connecting block 1, and a rotating block is fixedly connected to the outer wall of the rotating shaft.
[0008] Furthermore, a gear is fixedly connected to the outer wall of the rotating shaft, and two racks are slidably connected to the inner wall of the second groove, both of which mesh with the gear.
[0009] Furthermore, slider 1 is slidably connected to the inner wall of each of the two grooves 1, the top of each slider 1 is fixedly connected to two racks respectively, and slider 2 is slidably connected to the inner wall of each of the two grooves 1.
[0010] Furthermore, the bottom of each of the two sliders is fixedly connected to a clamping plate, the top of each of the two clamping plates is fixedly connected to the two sliders, and several slots are provided on the side of each of the two clamping plates that are close to each other.
[0011] Furthermore, a handle is slidably connected to the outer wall of the rotating block, a limit block is fixedly connected to the outer wall of the rotating block, a groove is provided on the inner wall of the handle, and the outer wall of the limit block is slidably connected to the groove.
[0012] Furthermore, the inner wall of the handle is provided with a plurality of grooves five, and each groove five is slidably connected to a slider three. Each slider three is adapted to a ratchet gear, and each slider three has a spring telescopic rod one fixedly connected to the side of each slider three that is far apart from each other. Each spring telescopic rod one has a side of each spring telescopic rod that is far apart from each other and is fixedly connected to a plurality of grooves five.
[0013] Furthermore, each of the two racks is fixedly connected to a connecting block 2 at its top, and each of the two connecting blocks 2 is fixedly connected to a spring telescopic rod 2 on the side of each connecting block 2 that is close to each other. The side of each of the two spring telescopic rods 2 that is close to each other is fixedly connected to two slots 1 respectively.
[0014] This utility model has the following beneficial effects:
[0015] 1. By setting up a clamping mechanism, during sampling, the clamping plate can be inserted into the sampling port. Then, the handle can be turned to make it drive the rotating shaft to rotate through the rotating block. When the rotating shaft rotates, it will drive the two racks to move closer to each other through the gear. When the two racks move closer to each other, the two clamping plates will move closer to each other under the action of the two sliders one and two sliders two, clamping the sample. The action of the groove three will prevent the sample from falling off. At the same time, the action of the anti-reverse mechanism will prevent the two clamping plates from automatically separating. This allows the sample to be effectively clamped during sampling, preventing the sample from falling off the device, thus ensuring the smooth progress of the sampling work and ensuring that the subsequent testing work will not be affected.
[0016] 2. By setting an anti-reverse mechanism, when the handle is turned, it will drive the rotating shaft to rotate through the rotating block. When the handle is turned, the ratchet will cause the slider three to slide into the slot five, causing the spring telescopic rod one to undergo elastic deformation and generate elastic force. When the handle is stopped, the slider three will be engaged with the ratchet under the elastic force of the spring telescopic rod one. At this time, the connecting block one will prevent the rotating shaft from reversing. When the rotating shaft rotates, it will drive the two racks to move closer to each other through the gear. At this time, the two connecting blocks two will cause the two spring telescopic rods two to undergo elastic deformation and generate elastic force. When it is necessary to remove the sample, the handle can be pulled, which will drive several sliders three away from the ratchet under the action of the limiting block and the slot four. Then the handle can be reversed. At this time, the two spring telescopic rods two will make the handle reversal easier, which can prevent the device from loosening during sampling and further ensure the stability of clamping. Moreover, after sampling is completed, the sample can be quickly removed from the sampling device, thereby saving the overall sampling time.

[0027] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-6 As shown, this utility model is a core-taking clamp for quality testing in municipal engineering projects. It includes a support block 1, a clamping mechanism 2, and an anti-reverse mechanism 3. The clamping mechanism 2 includes two slots 201 formed at the bottom of the support block 1, and a second slot 202 formed inside the support block 1, communicating with the two slots 201. A rotating shaft 203 is rotatably connected to the inner wall of the support block 1, with its top extending outside the support block 1 and its bottom extending into the second slot 202. A gear 204 is fixedly connected to the outer wall of the rotating shaft 203. Two racks 205 are slidably connected to the inner wall of the second slot 202, both of which mesh with the gear 204. Each slot 201 has a sliding block 206 slidably connected to its inner wall. The tops of the two sliding blocks 206 are fixedly connected to the two racks 205 respectively. Each slot 201 has a sliding block 207 slidably connected to its inner wall. Each sliding block 206 has a clamping plate 208 fixedly connected to its bottom. The tops of the two clamping plates 208 are fixedly connected to the two sliding blocks 207 respectively. Each clamping plate 208 has several slots 209 on its side that is close to each other. By setting up the clamping mechanism 2, the sample can be effectively clamped during sampling to prevent the sample from falling off the device, thereby ensuring the smooth progress of the sampling work and ensuring that the subsequent testing work will not be affected.
[0029] The anti-reverse mechanism 3 includes a connecting block 301 fixedly connected to the top of the support block 1. A ratchet 302 is fixedly connected to the outer wall of the connecting block 301. A rotating block 303 is fixedly connected to the outer wall of the rotating shaft 203. A handle 304 is slidably connected to the outer wall of the rotating block 303. A limit block 305 is fixedly connected to the outer wall of the rotating block 303. A groove 306 is formed on the inner wall of the handle 304. The outer wall of the limit block 305 is slidably connected to the groove 306. Several grooves 307 are formed on the inner wall of the handle 304. Sliding blocks 308 are slidably connected to the inner walls of the grooves 307. The sliding blocks 308 are all adapted to the ratchet 302. The sliding blocks 308 interact with each other. On the far side, spring telescopic rods 309 are fixedly connected. The far sides of several spring telescopic rods 309 are fixedly connected to several slots 307. Connecting blocks 310 are fixedly connected to the top of two racks 205. Spring telescopic rods 311 are fixedly connected to the close sides of two connecting blocks 310. The close sides of two spring telescopic rods 311 are fixedly connected to two slots 201. By setting an anti-reverse mechanism 3, the device can be prevented from loosening during sampling, which further ensures the stability of clamping. Moreover, after sampling is completed, the sample can be quickly removed from the sampling device, thereby saving the overall time of sampling work.
[0030] A specific application of this embodiment is as follows: In use, the device can be moved to the appropriate position, and then the clamp 208 can be inserted into the sampling port. The handle 304 can then be rotated, causing the rotating shaft 203 to rotate via the rotating block 303. When the handle 304 rotates, the ratchet 302 causes the slider 308 to slide into the slot 307, causing the spring telescopic rod 309 to elastically deform and generate elastic force. When the handle 304 is stopped, the slider 308, under the elastic force of the spring telescopic rod 309, will engage with the ratchet 302. At this time, the connecting block 301 will prevent the rotating shaft 203 from reversing. When the rotating shaft 203 rotates, the gear 204 will drive the two racks 205 to move closer together. At this time, under the action of the two connecting blocks 310, the two spring telescopic rods 311 will undergo elastic deformation and generate elastic force. When the two racks 205 approach each other, under the action of the two sliders 206 and the two sliders 207, the two clamping plates 208 will move closer to each other and clamp the sample. Under the action of the groove 209, the sample will be prevented from falling off. At the same time, under the action of the anti-reverse mechanism 3, the two clamping plates 208 will be prevented from automatically separating. When it is necessary to remove the sample, the handle 304 can be pulled, so that under the action of the limit block 305 and the groove 306, several sliders 308 will move away from the ratchet 302. Then the handle 304 can be reversed. At this time, under the action of the two spring telescopic rods 311, the reverse of the handle 304 is easier.
