Embodiment 1

[0031] A compaction instrument for road construction test, such as figure 1As shown, it includes a base 1, a bracket 2, a bracket 201, a horizontal plate 2011, a horizontal plate 2012, a horizontal bar 202, a motor 3, a pulley 301, a toggle assembly, a belt 302, and a pressing assembly And the pressure measuring barrel assembly, the upper side of the base 1 is equipped with a bracket 2, a bracket 2 201 and a motor 3, the bracket 2 and the bracket 201 are fixed side by side on the upper side of the base 1, and the bracket 2 is located on the right side of the bracket 2 201 The first horizontal plate 2011 and the second horizontal plate 2012 are fixedly connected to the lower end of the second bracket 201, the first horizontal plate 2011 is located above the second horizontal plate 2012, the motor 3 is fixedly connected to the upper side of the base 1, and the motor 3 is located between the first bracket 2 and the second bracket In the middle of 201, the output shaft end of moto...

Embodiment 2

[0034] On the basis of Example 1, such as Figure 2-6 As shown, the toggle assembly includes a rotating shaft 203, a wheel 204, and a dial 205. The front and rear ends of the rotating shaft 203 are rotatably connected to the middle of the cross bar 202, and the wheel 204 is fixedly connected to the middle of the rotating shaft 203. Rotating shaft 1 203 passes through the center of the wheel 204. Two dials 205 are arranged symmetrically along the center of the wheel 204. The dial 205 is fixedly connected to the peripheral edge of the wheel 204. The dial 205 touches the pressing assembly.

[0035] After the power is transmitted to the belt one 302, the belt one 302 will drive the wheel 204 to rotate, and the dial 205 on the wheel 204 will also rotate accordingly, and the dial 205 will touch the pressing assembly during the movement, so that It plays a role in allowing the rotation of the wave device to drive the pressing component.

[0036] The pressing assembly includes a stra...

Embodiment 3

[0045] On the basis of Example 2, such as Figure 7-10 Shown, also include strong spring one 209, cross bar two 208 and strong spring two 210, cross bar two 208 are fixedly connected in the middle part of T slide bar 207, and the front and rear ends of cross bar two 208 are respectively fixedly connected with strong spring one 209 and strong spring two 210, the lower end of strong spring one 209 and strong spring two 210 is fixedly connected on base 1 upper side.

[0046] In order to make the crushing post 2072 have greater strength in the process of smashing down, the two ends of the cross bar two 208 are connected with a strong spring one 209 and a strong spring two 210, and the lower ends of the strong spring one 209 and the two strong spring 210 are connected on the On the base 1, in this way, a greater downward force can be applied to the crushing column 2072, which can make the core sample crushed more firmly.

[0047] Also include small support plate 6, shaft two 601, ...

Abstract

The invention relates to road quality assessment test equipment, in particular to a compactor for a highway construction test. The invention aims to provide the compactor for the highway constructiontest, which is convenient for adjusting the proportion of a mixed core sample, convenient for taking out the tested core sample and simple and convenient to operate. According to the technical scheme,the compactor for the highway construction test comprises a base, a first support, a second support and the like. The first support, the second support and a motor are installed on the base, and thefirst support and the second support are fixedly connected to one side of the base side by side. A striking and pressing assembly can achieve up-down reciprocating smashing and pressing through a poking assembly; the striking and pressing assembly can be used for carrying out striking and pressing test on the core sample in a pressure measuring barrel assembly; the pressure measuring barrel assembly can rotate, so that the core sample in the pressure bearing barrel can be uniformly smashed and pressed; a buckle assembly is arranged in the pressure measuring barrel assembly and can take out thesmashed and pressed core sample; and the shifting assembly, the striking and pressing assembly and the pressure measuring barrel assembly are matched with one another, so that the core sample can besimply and efficiently tested.

Description

technical field [0001] The invention relates to a road quality assessment test equipment, in particular to a compaction instrument for road construction test. Background technique [0002] At present, roads are mainly paved with mixed materials such as gravel, mineral powder and asphalt, and the important basis for the quality supervision of paving projects is the detection data of pavement core samples. Indispensable device. [0003] After retrieval, the patent document with the application number 201620173451.X discloses a compaction instrument for road construction test, including a body, and a base, a side box and a cylinder on the body, a base at the bottom of the body, and a side box on the base. There is a cylinder on one side of the side box, the cylinder is connected to the cylinder shaft, and the connection between the cylinder and the cylinder shaft is provided with an anti-slip block and a limit block, and the two sides of the anti-slip block are symmetrically p...
