[0002] Devices used in highway engineering for testing pavement permeability are generally referred to as pavement permeability test instruments or equipment. These devices are designed to assess the permeability of a road surface, i.e. the ability of a road surface to penetrate water.

[0003] After searching, the Chinese patent announcement number: CN 218271882 U discloses a ground permeability detection device for highway engineering, including a base, a detector is arranged on the top of the base, a fixing assembly is arranged on the outside of the detector, both sides of the top of the base are fixedly connected with a fixing seat, the inner wall of the fixing seat is slidably connected with a mounting seat, and the inner wall of the mounting seat is provided with a fixing rod. The ground permeability detection device for highway engineering provided by the utility model solves the problem that it is often necessary to conduct permeability detection on the road surface in highway engineering. When conducting the detection, it is generally necessary to use a concrete permeability tester. In the prior art, it is generally placed on a trolley for movement. However, due to the large size and heavy weight of the traditional detector, it is easy to shake or even fall when it is moved on the trolley, and the stability is poor, the safety is low, and it is not conducive to the use of the staff.

[0004] In the prior art, on the one hand, although the device can prevent the detector from shaking or falling, in actual installations, the sizes of the detectors are different, and the device can only adapt to the detectors of the same model and cannot be changed according to the size of the detector. On the other hand, although the existing cart has a self-locking function, long-term use will cause the locking function to decrease, and it is impossible to increase the stability of the device during the detection process. Therefore, a pavement permeability detection device for highway engineering is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a road permeability detection device for highway engineering, aiming to improve the problem that the prior art cannot be used for detectors of different sizes.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pavement permeability detection device for highway engineering, comprising a cart, the outer wall of the cart is fixedly connected to a fixing ring, the middle part of the fixing ring is penetrated and slidably connected to a connecting rod, the top end of the fixing ring is elastically connected to a limiting block via a reset spring, the right end of the connecting rod is fixedly connected to a fixing plate, the side wall of the fixing plate is hinged with a splint via a hinge rod, and a detection mechanism is arranged at the top of the cart.

[0011] As a further description of the above technical solution:

[0012] The top end of the fixing ring is fixedly connected to one end of the return spring, and the other end of the return spring is fixedly connected to the inner side wall of the limiting block.

[0013] As a further description of the above technical solution:

[0014] The limiting block penetrates and is slidably connected to the inner wall of the fixing ring, and the limiting block is plugged into the outer wall of the connecting rod.

[0015] As a further description of the above technical solution:

[0016] The connecting rod passes through and is slidably connected to the inner wall of the cart.

[0017] As a further description of the above technical solution:

[0018] The side wall of the fixed plate is hinged to one end of the hinge rod, the other end of the hinge rod is hinged to the bottom end of the clamping plate, and the clamping plate penetrates and is slidably connected to the inner wall of the cart.

[0019] As a further description of the above technical solution:

It is simple and convenient in actual use, and the practicality of the device is improved to a certain extent.

[0023] 2.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3The utility model provides an embodiment of a road permeability detection device for highway engineering, comprising a cart 1, a fixing ring 2 is fixedly connected to the outer wall of the cart 1, a connecting rod 3 is passed through and slidably connected to the middle part of the fixing ring 2, and the fixing plate 6 and the hinge rod 7 are moved by the connecting rod 3, and the top of the fixing ring 2 is elastically connected to the limiting block 5 by the reset spring 4, and the limiting block 5 is an inclined surface. When squeezed, the limiting block 5 will slide along the inner wall of the fixing ring 2, and the right end of the connecting rod 3 is fixedly connected to the fixing plate 6, and the two ends of the fixing plate 6 are open, so that the opening can be hinged to the hinge rod 7, and the side wall of the fixing plate 6 is hinged with a splint 8 through the hinge rod 7, which contacts and fixes the detector 9 through the splint 8 to avoid shaking and falling. The contact surface between the splint 8 and the detector 9 is made of rubber material, which can increase the friction with the detector 9 to make it more stable, and a detection mechanism is arranged on the top of the cart 1.

[0033] Reference Figure 3-Figure 4 The inner wall of the cart 1 is threadedly connected with a threaded rod 10, and the inner wall of the cart 1 is provided with a pattern matching the threaded rod 10, so that the threaded rod 10 can move vertically along the cart 1, and the bottom end of the threaded rod 10 is rotatably connected with a bottom plate 11, and the bottom end of the bottom plate 11 is fixedly connected with a protrusion 12, which is made of rubber material and can make the protrusion 12 contact with the ground to increase the friction between the device and the ground. The top of the bottom plate 11 is fixedly connected with a guide tube 13, which can make the bottom plate 11 move vertically, and the moving trajectory will not be offset, and the guide tube 13 passes through and is slidably connected to the inner wall of the cart 1.

[0034] Reference Figure 1-Figure 3 The top of the fixing ring 2 is fixedly connected to one end of the return spring 4. When the limit block 5 moves upward, the return spring 4 will be stretched. When resetting, the elastic force of the return spring 4 is used to return the limit block 5. The other end of the return spring 4 is fixedly connected to the inner side wall of the limit block 5. The limit block 5 penetrates and is slidably connected to the inner wall of the fixing ring 2. The limit block 5 is plugged into the outer wall of the connecting rod 3. The outer wall of the connecting rod 3 is provided with a plurality of notches corresponding to the limit block 5. The limit block 5 is plugged into it to limit the connecting rod 3 in one direction. The connecting rod 3 penetrates and is slidably connected to the inner wall of the cart 1. The side wall of the fixed plate 6 is hinged to one end of the hinged rod 7. Since the length of the hinged rod 7 is fixed, when the fixed plate 6 moves to the left with one end of the hinged rod 7, the other end of the hinged rod 7 will bring the splint 8 closer to each other. When the fixed plate 6 moves to the right with one end of the hinged rod 7, the other end of the hinged rod 7 will bring the splint 8 away from the detector 9. The other end of the hinged rod 7 is hinged to the bottom end of the splint 8. The splint 8 penetrates and is slidably connected to the inner wall of the cart 1. The cart 1 is provided with a slot for the corresponding sliding of the splint 8. The detection mechanism includes a detector 9, and the detector 9 is placed on the top of the cart 1.

[0035] Working principle: First, when you need to fix the detectors 9 of different sizes, just follow Figure 1 Place the detector 9 between the two sets of clamps 8, then pull the connecting rod 3 outward to move the fixed plate 6 and one end of the hinged rod 7, then the hinged rod 7 will bring the clamps 8 closer to each other and clamp the detector 9, which can be suitable for detectors 9 of different sizes. When the connecting rod 3 moves outward, the outer wall groove of the connecting rod 3 will squeeze the inclined surface of the limit block 5, so that the limit block 5 moves upward and stretches the reset spring 4. When the limit block 5 coincides with the outer wall groove of the next connecting rod 3, the reverse elastic force of the reset spring 4 is used to reset the limit block 5 and plug it into it, thereby completing the unidirectional limit of the entire connecting rod 3.

[0036] During the use of the detector 9, the threaded rod 10 is rotated to move the threaded rod 10 with the base plate 11, the protrusion 12 and the guide tube 13 downward, so that the protrusion 12 contacts the ground to increase the contact area between the device and the ground, as well as the friction force, thereby improving the stability of the entire device during use. After use, when it is necessary to move to the next detection point, the threaded rod 10 only needs to be rotated in the opposite direction to move the threaded rod 10 with the base plate 11, the protrusion 12 and the guide tube 13 upward and reset, so that the protrusion 12 is not in contact with the ground.

[0037] When it is necessary to release the fixation of the detector 9, it is only necessary to move the limit block 5 upwards and stretch the reset spring 4, and then push the connecting rod 3 inward to move the fixing plate 6 and one end of the hinged rod 7, so that the hinged rod 7 at the other end and the clamping plate 8 are separated from each other to release the limit of the entire detector 9, and finally release the limit block 5 and use the reverse elastic force of the reset spring 4 to restore the limit block 5 to the initial position, which is convenient for subsequent reuse.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
