The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0034] As Figures 1 to 4 shown, an embodiment of the present application provides a hydraulic sampling device, which includes a platform device 1, a lifting platform 2, a hydraulic cylinder 3, a sliding seat 4, and a slide rail 5.

[0035] A slide rail 5 is arranged on the platform device 1 along the horizontal direction.

[0036] The sliding seat 4 is slidably installed on the slide rail 5.

[0037] The cylinder block 31 of the hydraulic cylinder 3 is installed at the lower part of the sliding seat 4, and the lower end of the piston rod 32 of the hydraulic cylinder 3 is fixedly connected to the lifting platform 2, and the piston rod 32 drives the lifting platform 2 to move up and down.

[0038] It should be noted that. As Figure 2 shown, the length of the single-sided slide rail 5 can be specifically set according to the actual width of the sampling space. The shape of the sliding seat 4 can be rectangular or arched. A frame-shaped handrail 21 is provided on the upper part of the lifting platform 2, which plays a certain safety role. When the device is in use, after the sampling vehicle arrives at the sampling area and stops, the staff on the platform device 1 stands steady on the lifting platform 2, and the sliding seat 4 slides on the slide rail 5 until the lifting platform 2 slides above the vehicle sampling port and is fixed. Then, the hydraulic cylinder 3 is started, so that the piston rod 32 drives the lifting platform 2 to descend to the vehicle roof, and then the staff conducts sampling. After the sampling work is completed, the lifting platform 2 rises back to the platform device 1, and the sampling vehicle drives away. Using this device for sampling can improve the safety of the sampling process, make the sampling work more convenient and fast, and solve the technical problems of time-consuming, laborious, and poor safety in the prior art.

[0039] In this embodiment, the number of the hydraulic cylinders 3 is two, and the two hydraulic cylinders 3 are symmetrically arranged on the left and right sides of the lifting platform 2.

[0040] It should be noted that. AsFigure 1 As shown, when the device is in use, the hydraulic cylinder 3 plays a role in lifting. The lifting height is adjusted according to the change of the size of the transport vehicle, and it can stably maintain the current state when it reaches the required height, solving the safety problem caused by improper operation of personnel.

[0041] In this embodiment, the platform device 1 includes two horizontally arranged cross beams 11, and the two cross beams 11 are respectively arranged on the front and rear sides of the sliding seat 4. A slide rail 5 is arranged on each cross beam 11.

[0042] It should be noted that. The positions of the two cross beams 11 on the platform device 1 are preferably at the top and maintain a certain distance. The sliding seat 4 is provided with a locking mechanism. When the sliding seat 4 moves to the designated position, the locking mechanism locks the sliding seat 4 at the current position of the slide rail 5. The locking mechanism in this application is a prior art, so it will not be described in detail. When the device is in use, after the sampling vehicle enters the sampling space, the sliding seat 4 can quickly adjust the position of the lifting platform 2 and fix the designated state, making the sampling work more convenient to implement and solving the problem of cumbersome work of manual handling devices.

[0043] In this embodiment, two sliders 41 are fixedly arranged at both the front and rear ends of the sliding seat 4.

[0044] On the side of the slider 41 away from the sliding seat 4, there is a sliding groove 42 that cooperates with the slide rail 5.

[0045] It should be noted that. The number of sliders 41 on one side of the sliding seat 4 is not less than two. When the slide rail 5 is symmetric in shape and slides on both sides, the stability of this sliding mechanism is higher. The sliding seat 4 is detachably installed on the slide rail 5, which is convenient for maintenance and replacement.

[0046] In this embodiment, an inner groove 111 is horizontally arranged on the cross beam 11.

[0047] The slide rail 5 is installed in the inner groove 111, and guide grooves 51 are arranged on both the upper and lower parts of the slide rail 5.

[0048] On both the upper and lower parts of the sliding groove 42 of the slider 41, there are sliding protrusions 43 that cooperate with the guide grooves 51.

[0049] It should be noted that. The bottom of the slide rail 5 is fixed to the inner groove 111 with bolts. The shape of the sliding protrusion 43 matches that of the guide groove 51. When the device is in use, the guide groove 51 has a limiting effect on the sliding protrusion 43, keeping the sliding seat 4 moving in a straight line and improving the stability of the device.

[0050] In this embodiment, balls 44 are arranged on the sliding protrusion 43.

[0051] The balls 44 are in contact with the guide grooves 51.

[0052] It should be noted that, as Figure 3 shown, the ball 44 protrudes from the sliding protrusion 43. Rollers can also be provided at the sliding protrusion 43. When the device is in use, the ball 44 has the characteristic of reducing friction, reducing the wear of the slide rail 5, so as to improve the durability of the device.

[0053] In this embodiment, the platform device 1 further includes longitudinal beams 12 and columns 13.

[0054] Columns 13 are provided at both the left and right ends of the cross beam 11, and the end of the cross beam 11 is connected to the column 13.

[0055] The longitudinal beam 12 is horizontally arranged between the front and rear columns 13, and the end of the longitudinal beam 12 is connected to the column 13.

[0056] It should be noted that, as Figure 1 、 Figure 4 shown, the longitudinal beam 12 is arranged at the top and middle of the platform device 1. The distance between the left and right columns 13 is four times the width of the oil tanker. When the device is in use, the sampling vehicle needs to drive between the left and right columns 13.

[0057] In this embodiment, the platform device 1 further includes a fixed platform 14, a diagonal brace 15, a guardrail 16 and a diagonal ladder 17.

[0058] The fixed platform 14 is arranged between the front and rear two columns 13.

[0059] Both ends of the diagonal brace 15 are respectively fixedly connected to the column 13 and the lower part of the fixed platform 14.

[0060] The guardrail 16 is arranged circumferentially on the upper part of the fixed platform 14.

[0061] It should be noted that, as Figure 1 shown, the height of the fixed platform 14 from the ground is 1.5 - 2 m higher than the height of the oil tanker. The diagonal brace 15 is used to support the fixed platform 14 to enhance the stability. One end of the diagonal ladder 17 is fixedly connected to one side of the fixed platform 14. The guardrail 16 plays a role in ensuring safety. When the device is in use, the staff reaches the fixed platform 14 through the diagonal ladder 17, and moves the lifting platform 2 to the side of the fixed platform 14 through the sliding seat 4, so as to facilitate the personnel to get onto the lifting platform 2.
