Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a sampling device for concrete detection in bridge construction. Background Technique

[0002] The construction of concrete pouring is a very important process in the main structure project of a bridge. Because bridge projects usually have the characteristics of high height and large span, the quality of concrete is directly related to the safety and service life of the bridge project. In order to evaluate the quality of concrete and ensure that it meets the design requirements and engineering standards, it is necessary to sample and detect the concrete before the construction of the main structure of the bridge, including the pouring of structures such as pile caps, pier columns, and capping beams.

[0003] The current methods for sampling and detecting concrete generally use a tank container to receive concrete from the end of the pump pipe of a concrete mixer, and then pour the concrete in the tank container into a slump cone for slump detection. However, this sampling method is prone to leakage from above the slump cone when pouring the concrete with the tank container, and the tank container filled with concrete is heavy. If it cannot be firmly grasped during pouring, it will collide with the slump cone and cause it to slip, resulting in the leakage of concrete in the cone and inaccurate slump detection.

[0004] Therefore, aiming at the situation that the existing concrete detection sampling tools and methods are prone to concrete leakage and slump cone displacement when pouring concrete into the slump cone, a sampling device integrated with the slump cone can be designed, which can quickly and stably transfer the concrete into the slump cone without pouring the concrete after sampling, reducing the operation difficulty. Content of the Utility Model

[0005] In order to overcome the problems that the existing concrete detection sampling tools and methods are prone to concrete leakage and slump cone displacement when pouring concrete into the slump cone.

[0006] The technical solution of the utility model is: a sampling device for concrete detection in bridge construction, including a sampling tank with scale marks on the outer wall, a slump cone, a through pipe, a base, a slot, a baffle, a sliding rod, a sliding sleeve and a sleeve; the lower end of the sampling tank is a conical structure and is integrally and fixedly connected with a through pipe, the upper end of the slump cone is connected and fixed with the through pipe through a hollow base, the sampling tank, the through pipe, the base and the slump cone are connected and penetrated from top to bottom to form a concrete falling channel, the base is a quadrilateral platform structure and is provided with a slot on one side, a baffle is inserted into the slot to close the falling channel, two parallel L-shaped sliding rods are arranged on one side of the upper end of the sampling tank, the horizontal part of the sliding rod is fixedly connected with the upper edge of the sampling tank, a sliding sleeve is sleeved on the vertical part of the sliding rod, and a sleeve with scale marks on the surface is fixedly connected to the outside of the sliding sleeve.

[0007] Preferably, the sampling tank is aligned with the discharge pipe of the concrete mixer, and the concrete is discharged into the sampling tank. Then, the slump cone is placed on the ground in the inspection area, the baffle is pulled out from the slot to open the material dropping channel, and the concrete in the sampling tank flows into the slump cone through the through pipe and the base. After the slump cone is filled, the baffle is inserted back to close the material dropping channel. Then, the sampling tank and the slump cone are vertically pulled up, and the concrete flows naturally. After a certain period of time, the slump height of the concrete is checked through the scale markings on the wrapper.

[0008] Preferably, a U-shaped footrest is fixedly connected between the lower ends of the two sliding sleeves, and a U-shaped handle parallel to the upper part of the footrest is fixedly connected between the upper ends of the sliding sleeves. When receiving concrete, the user holds the handle with the hand to keep the sampling tank stable under the discharge pipe of the mixer. When pulling up the sampling tank and the slump cone, first step on the footrest with the foot, and then pull the sampling tank to make the sliding rod move vertically and stably along the sliding sleeve to prevent the slump cone from shaking left and right.

[0009] Preferably, a hoop is fixedly connected between the upper ends of the horizontal parts of the sliding rod. The discharge pipe of the concrete mixer passes through one side of the hoop and extends into the sampling tank. The hoop is used to position the discharge pipe of the mixer when receiving concrete to prevent the discharge pipe from swinging due to the pressure during concrete delivery. When lifting the sampling tank and the slump cone, the hoop can also be grasped by hand to apply force.

[0010] Preferably, except for one side of the slot, lamp beads are fixedly installed on the outer walls of the other three sides of the base. The lamp beads are powered by a power source built into the base. When sampling and detecting concrete at night, the lamp beads are turned on to provide illumination around the sampling and detection environment, facilitating operation and enabling the user to observe the scale markings on the sampling tank and the wrapper.

[0011] Preferably, one end of the baffle outside the slot is fixedly connected with an end plate closely attached to the side wall of the base. A U-shaped handle is installed on the surface of the end plate. A locking member for fixing the baffle in the slot is arranged between the end plate and the base. The baffle is horizontally inserted into the slot. When the end plate abuts against the surface of the base, the material dropping channel is completely closed. As long as the baffle is pulled out a certain length, the material dropping channel can be opened.

[0012] Preferably, the locking member is a magnetic sheet. There are two groups of magnetic sheets, which are respectively embedded and installed on the end plate and the side wall of the base. The two magnetic sheets are magnetically adsorbed and fixed. After loosening the handle, due to the adsorption of the magnetic sheets, the end plate remains closely attached to the surface of the base, making the baffle unable to loosen out of the slot and keeping the material dropping channel closed.

[0013] Preferably, the locking member includes a pin hole and a spring pin; a pin hole is provided on the side wall of the base platform above the slot, one side of the end plate is fixedly connected with a spring pin inserted into the pin hole, one end of the spring on the spring pin is fixed to the end plate, and the other end is fixed to the inner wall of the groove on the base platform. After the handle is released, under the elastic contraction of the spring, the end plate is pulled closer to the base platform, so that the pin in the spring pin is pushed into the pin hole, and the spring force is used to prevent the retaining piece from loosening in the slot, keeping the blanking channel closed.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. Through the integrated design of the sampling tank and the slump cone, after sampling the concrete, it can be quickly and vertically unloaded into the slump cone for testing. Compared with the original operation method, manual pouring of concrete is avoided, the operation difficulty is low, and the situation of concrete overflow or slump cone movement caused by unstable pouring will not occur;

[0016] 2. By using the sliding socket structure of the sliding rod and the sliding sleeve, the slump cone can be vertically pulled out when testing the concrete. Compared with the original method of taking out the slump cone, it is not easy to cause the slump cone to squeeze and touch the concrete due to hand shaking, and the slump test is accurate;

[0017] 3. One person can complete the two-step operation of stepping on the foot pedal and pulling out the sampling tank. In addition, when checking the slump height of the concrete, only the person stepping on the foot pedal needs to squat down close to the wrapper, and keep the hands in the action of lifting the sampling tank and the slump cone to observe the corresponding position of the concrete top surface and the scale on the wrapper. Therefore, there is no need for two people to complete the measurement operation;

[0018] 4. The locking member is used to control the retaining piece not to fall out of the slot, and it is simple to insert and remove the retaining piece. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0029] The present utility model will be further described below with reference to the drawings and embodiments.

[0030] Please refer to Figures 1 - 9, the utility model provides a sampling device for testing bridge construction concrete, which includes a sampling tank 1 with scale marks on the outer wall, a slump cone 2, a through pipe 3, a base 4, a slot 5, a baffle 6, a sliding rod 10, a sliding sleeve 11 and a sleeve 12; the lower end of the sampling tank 1 is a conical structure and is integrally and fixedly connected with the through pipe 3, the upper end of the slump cone 2 is connected and fixed with the through pipe 3 through a hollow base 4 inside, the sampling tank 1, the through pipe 3, the base 4 and the slump cone 2 are connected through from top to bottom to form a concrete falling channel, the base 4 is a quadrilateral platform structure and is provided with a slot 5 on one side, and a baffle 6 is inserted into the slot 5 to close the falling channel, two parallel L-shaped sliding rods 10 are arranged on one side of the upper end of the sampling tank 1, the horizontal part of the sliding rod 10 is fixedly connected with the upper edge of the sampling tank 1, a sliding sleeve 11 is sleeved on the vertical part of the sliding rod 10, and a sleeve 12 with scale marks on the surface is fixedly connected to the outside of the sliding sleeve 11. The sampling tank 1 is aligned with the discharge pipe of the concrete mixer, and the concrete is unloaded into the sampling tank 1. Then, the slump cone 2 is placed on the ground in the detection area, the baffle 6 is pulled out of the slot 5 to open the falling channel, and the concrete in the sampling tank 1 flows into the slump cone 2 through the through pipe 3 and the base 4. After the slump cone 2 is filled, the baffle 6 is inserted back to close the falling channel, and then the sampling tank 1 and the slump cone 2 are vertically pulled up. The concrete flows naturally. After a certain period of time, the slump height of the concrete is checked through the scale marks on the sleeve 12.

[0031] Please refer to Figures 1 - 6 , a U-shaped footrest 13 is fixedly connected between the lower ends of the two sliding sleeves 11, and a U-shaped handle 14 parallel to the upper side of the footrest 13 is fixedly connected between the upper ends of the sliding sleeves 11. When receiving concrete, the user holds the handle 14 with the hand to make the sampling tank 1 stable under the discharge pipe of the mixer. When pulling up the sampling tank 1 and the slump cone 2, first step on the footrest 13 with the foot, and then pull the sampling tank 1 to make the sliding rod 10 move vertically and stably along the sliding sleeve 11 to prevent the slump cone 2 from shaking left and right. A hoop 15 is fixedly connected between the upper ends of the horizontal parts of the sliding rod 10, and the discharge pipe of the concrete mixer passes through one side of the hoop 15 and extends into the sampling tank 1. The hoop 15 is used to position the discharge pipe of the mixer when receiving concrete to prevent the discharge pipe from swinging due to the pressure when the concrete is sent out. When pulling up the sampling tank 1 and the slump cone 2, the hoop 15 can also be grasped by hand to apply force.

[0032] Please refer to Figures 1 - 5 , Figures 7 - 9, except on one side of the slot 5, lamp beads 16 are fixedly installed on the outer walls of the other three sides of the base 4. The lamp beads 16 are powered by a power supply built into the base 4. When sampling and detecting concrete at night, the lamp beads 16 are turned on to provide illumination around the sampling and detection environment, facilitating operation and enabling users to observe the scale markings on the sampling tank 1 and the wrapper 12. One end of the baffle 6 outside the slot 5 is fixedly connected to an end plate 7 that closely adheres to the side wall of the base 4. A U-shaped handle 8 is installed on the surface of the end plate 7. A locking member for fixing the baffle 6 in the slot 5 is provided between the end plate 7 and the base 4. After the concrete in the slump cone 2 has finished falling, the liquid level of the concrete in the sampling tank 1 will no longer drop. At this time, inserting the baffle 6 into the slot 5 can cut off the concrete falling channel from the top surface of the slump cone 2. The baffle 6 is horizontally inserted into the slot 5. When the end plate 7 abuts against the surface of the base 4, the falling channel is completely closed. As long as the baffle 6 is pulled out a certain length, the falling channel can be opened.

[0033] Example 1: Please refer to Figure 7 , in this embodiment, the locking member is a magnetic sheet 901. There are two groups of magnetic sheets 901, which are respectively embedded and installed on the end plate 7 and the side wall of the base 4. The two magnetic sheets 901 are magnetically adsorbed and fixed to each other. After loosening the handle 8, under the adsorption of the magnetic sheet 901, the end plate 7 remains closely attached to the surface of the base 4, preventing the baffle 6 from loosening out of the slot 5 and keeping the falling channel closed.

[0034] Example 2: Please refer to Figure 8 , in this embodiment, the locking member includes a pin hole 902 and a spring pin 903; a pin hole 902 is provided on the side wall of the base 4 above the slot 5. One side of the end plate 7 is fixedly connected to a spring pin 903 inserted into the pin hole 902. One end of the spring on the spring pin 903 is fixed to the end plate 7, and the other end is fixed to the inner wall of the groove on the base 4. After loosening the handle 8, under the elastic contraction of the spring, the end plate 7 is pulled closer to the base 4, causing the pin in the spring pin 903 to be pushed into the pin hole 902, and using the spring tension to prevent the baffle 6 from loosening out of the slot 5 and keeping the falling channel closed.

[0035] Through the above steps, through the integrated design of the sampling tank 1 and the slump bucket 2, after sampling concrete, it can be quickly and vertically unloaded into the slump bucket 2 for testing. Compared with the original operation method, manual pouring of concrete is eliminated, the operation difficulty is low, and there will be no situation where the pouring is unstable and causes concrete overflow or the slump bucket 2 to move. In addition to using the sampling tank 1 to receive concrete and drop the material, structures such as the handle 14 and the foot pedal 13 are also used. When pouring concrete, you only need to step on the foot pedal 13 to stabilize the entire equipment, and there is no need to squat and hold it with your hands, which is obviously easier; and sampling The volume of the sample tank 1 is much larger than the capacity of the slump bucket 2. Therefore, when pouring concrete directly into the slump bucket 2, it will not happen that the concrete overflows to the ground due to the difficulty in controlling the pouring volume and pouring speed, causing waste. When the sampling tank 1 is used to receive materials, even if the amount of material received is large, the excess concrete can be recycled or made into test blocks for strength, stiffness and other tests, so as to solve the problem that the existing concrete testing sampling tools and methods are prone to concrete leakage and slump bucket 2 displacement when pouring concrete into the slump bucket 2.
