[0019] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0020] A sliding plate assembly fixture for testing the slip resistance coefficient of steel structures includes an assembly platform 1, with support legs 29 installed at the bottom of the assembly platform 1.

[0021] A lifting seat 2 is installed on the assembly table 1, and a drive unit is installed between the assembly table 1 and the lifting seat 2. The drive unit drives the lifting seat 2 to move up and down relative to the assembly table 1.

[0022] The drive unit includes a screw jack 20 and a guide assembly. The screw jack 20 is fixedly installed on the assembly table 1. The screw 30 on the screw jack 20 can only move linearly and cannot rotate. The top of the screw 30 on the screw jack 20 is fixedly connected to the top of the lifting seat 2. A flange is installed on the top of the screw 30, and the flange is connected to the bottom surface of the lifting seat 2 by bolts.

[0023] The input shaft of the screw jack 20 is connected to a throttle 21. This invention allows for convenient rotation of the input shaft of the screw jack 20 by providing the throttle 21. The input shaft of the screw jack 20 is connected to an extension rod 23, with the throttle 21 mounted at one end. A bearing seat 24 is installed between the extension rod 23 and the assembly table 1. The extension rod 23 passes through a bearing within the bearing seat 24 and is supported by the bearing seat 24. This invention allows the throttle 21 to extend beyond the assembly table 1 via the extension rod 23, facilitating operation of the throttle 21.

[0024] The guiding assembly includes guide posts 22 installed at the bottom of the lifting base 2 and guide holes on the assembly platform 1 corresponding to each guide post 22. The guide posts 22 are inserted into the guide holes. Four guide posts 22 are installed at the bottom of the lifting base 2. The guiding assembly of this invention allows the lifting base 2 to only move up and down.

[0025] The lifting seat 2 is equipped with left and right longitudinal slide rails 3 on its top. A longitudinal sliding seat 4 is slidably mounted on the longitudinal slide rails 3. Baffles 31 are installed at the front and rear ends of the longitudinal slide rails 3, and the baffles 31 on both sides can limit the forward and backward movement of the longitudinal sliding seat 4 to prevent the longitudinal sliding seat 4 from sliding off the longitudinal slide rails 3. A longitudinal slider 25 that cooperates with the longitudinal slide rails 3 is installed at the bottom of the longitudinal sliding seat 4. In this invention, the longitudinal sliding seat 4 moves back and forth relative to the longitudinal slide rails 3 through the longitudinal slider 25, so as to facilitate the longitudinal alignment of multiple bolts on the sliding plate test assembly with the rotating sleeve 12. The fixed sleeve 7 and the rotating sleeve 12 are of the same height and are arranged opposite each other.

[0026] The top of the longitudinal sliding seat 4 is equipped with a transverse slide rail 5, and a transverse sliding seat 6 is slidably mounted on the transverse slide rail 5. A transverse slider 26, which cooperates with the transverse slide rail 5, is installed at the bottom of the transverse sliding seat 6. In this invention, the transverse sliding seat 6 moves left and right relative to the transverse slide rail 5 via the transverse slider 26, facilitating the transverse insertion of the nut on the sliding plate test assembly into the fixed sleeve 7, and the transverse insertion of the bolt on the sliding plate test assembly into the rotating sleeve 12.

[0027] Clamping plate assemblies are respectively installed on the front and rear sides of the transverse sliding seat 6. Each clamping plate assembly includes left and right clamping plates 27. One of the clamping plates 27 has a threaded hole for fastening, and a fastening bolt 28 is threaded into the threaded hole. The clamping plate assembly of this invention is used to fix the sliding plates at both ends of the sliding plate test assembly. In the sliding plate test assembly, the sliding plates at both ends can be called end sliding plates, and the two side sliding plates used to connect the two end sliding plates can be called side sliding plates. When assembling multiple sliding plates, we first place the end sliding plates at both ends into the two side clamping plates 27 of the clamping plate assembly, and then rotate the fastening bolts 28 on the clamping plates 27 to make the two side fastening bolts 28 respectively abut against the end sliding plates in the two side clamping plate assembly, thereby fixing the sliding plate test assembly. The purpose of the end sliding plates at both ends of the test assembly is to provide two connecting holes on each side of the opposite side of the end sliding plates, and four connecting holes on each side sliding plate. Then, place the two side sliding plates on both sides of the end sliding plates, and align the four connecting holes on the side sliding plates with the connecting holes on the two end sliding plates. The end sliding plate is between the two side sliding plates. Then, the long bolt is passed through the side sliding plate, the end sliding plate, the axial force sensor, and the side sliding plate in sequence. Finally, the nut is screwed on the long bolt, and the axial force sensor is between the nut and the side sliding plate.

[0028] The assembly platform 1 has a clamping frame and a tightening shaft 10 installed on the left and right sides of the lifting seat 2, respectively. A fixing sleeve 7 is detachably installed on the clamping frame.

[0029] The clamping frame includes two vertical plates 13, which can be installed on the assembly table 1 by welding or by bolts and nuts.

[0030] A fixing post 8 is installed on the upper side of the clamping frame. The fixing post 8 is fixedly installed between the two vertical plates 13 by bolts. Multiple threaded holes can be opened on both sides of the fixing post 8, and multiple through holes are opened on the two vertical plates 13. During installation, the bolts are inserted into the through holes on the vertical plates 13 and the threaded holes on the fixing post 8 in sequence. The fixing post 8 can also be connected to the two vertical plates 13 by welding.

[0031] A sliding column 9 is slidably installed in the sliding cavity of the fixed column 8. The sliding column 9 is inserted into the sliding cavity of the fixed column 8 and can slide along the sliding cavity. A fixing sleeve 7 is detachably installed at the front end of the sliding column 9. In application, the fixing sleeve 7 is used to fix the nut on the sliding plate test assembly.

[0032] The front end of the fixing sleeve 7 has an inner hole. The depth of the inner hole of the fixing sleeve 7 is greater than the thickness of the nut, so that the front end of the nut and bolt can be inserted into the inner hole of the fixing sleeve 7. The inner hole of the fixing sleeve 7 can be designed as an internal hexagonal hole. When the nut specification on the sliding plate test assembly changes, we also need to replace the fixing sleeve 7 accordingly.

[0033] The sliding column 9 has a first connector 16 installed at its front end. The rear end of the fixed sleeve 7 has a socket for inserting the first connector 16. The first connector 16 and the fixed sleeve 7 each have a mating through hole. A first fixing pin 17 is inserted between the through hole of the first connector 16 and the through hole of the fixed sleeve 7. A nut is installed at one end of the first fixing pin 17. When installing the fixed sleeve 7, the first connector 16 is first inserted into the socket at the rear end of the fixed sleeve 7, aligning the through hole on the fixed sleeve 7 with the through hole on the first connector 16. Then, the first fixing pin 17 is passed through the through holes on the fixed sleeve 7 and the first connector 16, and a nut is installed at one end of the first fixing pin 17. The first fixing pin 17 is a bolt.

[0034] A limiting groove 14 is formed on the side wall of the fixed column 8, and the limiting groove 14 communicates with the inner cavity of the fixed column 8. A limiting rod 15 is installed on the sliding column 9 and inserted into the limiting groove 14. By setting the limiting groove 14 and the limiting rod 15, this utility model can effectively limit the sliding of the sliding column 9 in the sliding cavity of the fixed column 8, and prevent the sliding column 9 from sliding out of the sliding cavity of the fixed column 8. When the limiting rod 15 contacts one end of the limiting groove 14, the limiting groove 14 can prevent the sliding column 9 from continuing to slide in this direction.

[0035] A rotating sleeve 12 is detachably mounted on the main shaft 11 of the tightening shaft 10. The tightening shaft 10 is existing technology and typically includes a housing. A servo motor and a reducer are installed inside the housing. The servo motor is connected to the reducer, and the output shaft of the reducer is connected to the main shaft 11. The main shaft 11 extends out of the housing, and the motor drives the main shaft 11 to rotate via the reducer. In application, the rotating sleeve 12 is used to rotate the bolts on the sliding plate test assembly.

[0036] The front end of the rotating sleeve 12 has an inner hole, which can be designed as an internal hexagonal hole. The bolt head of the long bolt in the sliding plate test assembly can be inserted into the inner hole of the rotating sleeve 12. When the bolt specifications on the sliding plate test assembly are changed, the rotating sleeve 12 also needs to be replaced accordingly.

[0037] A second connector 18 is mounted on the front end of the main shaft 11. The rotating sleeve 12 is detachably connected to the second connector 18. The second connector 18 and the rotating sleeve 12 are connected by a second fixing pin 19, one end of which is fitted with a nut. The rear end of the rotating sleeve 12 has an insertion hole for the second connector 18. The second connector 18 and the rotating sleeve 12 each have mating through holes. The second fixing pin 19 is inserted between the through holes of the second connector 18 and the rotating sleeve 12, and one end of the second fixing pin 19 is fitted with a nut. When installing the rotating sleeve 12, the second connector 18 is first inserted into the insertion hole at the rear end of the rotating sleeve 12, aligning the through holes on the rotating sleeve 12 with those on the second connector 18. Then, the second fixing pin 19 is passed through the through holes on the rotating sleeve 12 and the second connector 18, and a nut is fitted to one end of the second fixing pin 19. The second fixing pin 19 is a bolt.

[0038] The usage process of this utility model is as follows: First, assemble multiple sliding plates, multiple bolts, and multiple axial force sensors. After assembly, the axial force sensors are located between the nuts and the sliding plates, as shown in the attached diagram. Figure 4 As shown; then turn the throttle 21, the screw jack 20 drives the lifting seat 2 to rise and fall, and then drives the sliding plate test assembly to rise and fall, so that the bolt and nut are at the same height as the rotating sleeve 12 and the fixed sleeve 7. Then pull the sliding column 9 outward, and at the same time move the longitudinal seat 4 and the transverse seat 6 so that one end of the nut and bolt is inserted into the inner hole of the fixed sleeve 7. Then push the sliding column 9 and the transverse seat 6 towards the tightening shaft 10 at the same time so that the bolt head is inserted into the inner hole of the rotating sleeve 12. Finally, turn on the switch of the tightening shaft 10, and the main shaft 11 drives the bolt to rotate through the rotating sleeve 12. The digital display connected to the axial force sensor will display the preload value. When the preload value reaches the predetermined value, the digital display can sound an alarm. At this time, the tightening shaft 10 is disconnected.
