[0019] A metal protective member processing device comprises a table top and a stopper located above the table top, wherein the table top is used to support the bottom of the metal protective member, and the stopper is used to limit the metal protective member to prevent the metal protective member from being displaced relative to the table top;

[0020] For ease of understanding, metal protective parts are explained. Figure 8 The diagram shows a portion of the structure remaining after the metal guard is divided into two parts, wherein the metal guard comprises an outer shell 61 with a single opening, and a cover 62 fixed to the outer shell 61 for closing the opening of the metal guard, and a pressure plate 63 integrally connected, welded or bolted to the cover 62, the pressure plate 63 divides the enclosed space inside the metal guard into two layers, the space in the lower layer is used for laying a counterweight, which is preferably a sandbag or a sack filled with gravel, and the pressure plate 63 is used to press down the top of the counterweight to prevent the counterweight from moving over adjacent configuration parts. This solution has high filling efficiency and low cost.

[0021] During processing, a large shell 61 can be hoisted above the top platform 31, with the opening of the shell 61 facing forward, and a stopper can be used to press against the wall at the rear end of the shell 61, and the counterweight can be pushed into the deepest part of the bottom of the shell 61 through the opening. Multiple counterweights can be placed one after another to cover the bottom of the shell 61. The stopper can prevent the friction generated by pushing in the counterweight from causing the thin shell 61 to move, thereby affecting the working efficiency. The shell 61 is preferably made of aluminum alloy, which is suitable for use as a warning or in environments where it is easy to collide with personnel vehicles. Steel is used in special environments, such as as a support for heavy objects or a protective object with the protected object as the main target.

[0022] To match the housing 61 of different sizes or shapes, at least one abutment is provided on each of the left and right sides of the rear, such as Figure 6 As shown, the structure of the stopper is preferably a column stopper 47 with a protruding columnar structure, and the axis of the columnar structure is vertical.

[0023] Furthermore, as described Figure 1 and 4 As shown, the table top is a top platform 31, the number of the top platforms 31 is four, the center lines of the four top platforms 31 form a quadrilateral, and two column-belted abutments 47 are located on the two top platforms 31 at the rear side; and an XY-axis displacement platform for adjusting the spacing between two adjacent top platforms 31 is also included;

[0024] Among them, Figures 2 to 5 As shown, the XY axis displacement platform adjustment includes: a linear drive mechanism I and a linear drive mechanism II;

[0025] Wherein, the linear drive mechanism I comprises a base frame 11, and two double-ended lead screws 12 extending forward and backward arranged above the base frame 11, the two double-ended lead screws 12 are arranged in a linear array in the left and right directions, the front and rear sides of the double-ended lead screws 12 have opposite thread rotation directions, the front and rear ends of each double-ended lead screw 12 are rotatably connected to a seat bearing I 13, the seat bearing I 13 is fixedly connected to the base frame 11, the two double-ended lead screws 12 are synchronously driven through a first pulley belt assembly, a first motor is installed on the base frame 11, and the first motor and one of the double-ended lead screws 12 are synchronously driven through a second pulley belt assembly;

[0026] When the first motor is started, the two double-ended screws 12 can be rotated synchronously. The two double-ended screws 12 are used to change the spacing between the two linear drive mechanisms II. The specific scheme is as follows:

[0027] The linear drive mechanism II includes a middle frame 21, two adjustment seats I22 respectively fixed on the left and right sides of the lower end of the middle frame 21, and two double-headed screws II24 extending left and right above the middle frame 21. The threads of the double-headed screws II24 on the left and right sides are opposite to each other. The two ends of each double-headed screw II24 are rotatably connected to a seat bearing III25, and the seat bearing III25 is fixed to the upper end of the middle frame 21. The two double-headed screws II24 are driven by the third pulley belt assembly to achieve synchronous transmission. A second motor is installed on the middle frame 21, and the second motor and one of the double-headed screws II24 are driven by the third pulley belt assembly to achieve synchronous transmission; the two adjustment seats I22 located on the rear side are respectively spirally driven on the rear side of the two double-headed screws 12, and the two adjustment seats I22 located on the front side are respectively spirally driven on the front side of the two double-headed screws 12. When the double-headed screw 12 rotates, the distance between the two middle frames 21 changes;

[0028] Furthermore, an adjustment seat Ⅱ34 is fixed to the front and rear sides of the lower end of each top platform 31. The top platform 31 located on the left rear side uses its own adjustment seat Ⅱ34 to spirally transmit to the left side of the two double-headed screws Ⅱ24 located on the rear side, and the top platform 31 located on the right rear side uses its own adjustment seat Ⅱ34 to spirally transmit to the right side of the two double-headed screws Ⅱ24 located on the rear side. The top platform 31 located on the left front side uses its own adjustment seat Ⅱ34 to spirally transmit to the left side of the two double-headed screws Ⅱ24 located on the front side, and the top platform 31 located on the right front side uses its own adjustment seat Ⅱ34 to spirally transmit to the right side of the two double-headed screws Ⅱ24 located on the front side; thereby, a linear drive mechanism Ⅱ is implemented with a top platform 31 on each side. When the double-headed screw Ⅱ24 rotates, the spacing between the top platforms 31 on the left and right sides changes. At this point, the four top platforms 31 can approach or move away from each other in the front-to-back direction and the left-to-right direction, supporting shells 61 of different sizes, and the column-belted abutment 47 on the top platform 31 can also abut against shells 61 of different sizes.

[0029] Further, the left and right sides of the rear side of the lower end of the base frame 11 are rotatably connected to a shaft I14, each shaft I14 is movably connected to a seat bearing II15, the seat bearing II15 is fixed to the ground, and the front side of the lower end of the base frame 11 is fixedly connected to a frame with straight slots 16, the straight slots on the frame with straight slots 16 extend front and back and are connected left and right, and the frame with straight slots 16 is inserted and slidably with a shaft II18 extending left and right, and the shaft II18 is driven by the telescopic cylinder I17 to achieve lifting and lowering to drive the frame with straight slots 16 to swing around the shaft I14, so that the top platform 31 is tilted backward, with the rear lower and the front higher. At this time, the rear side of the column abutment 47 is used to abut the rear end of the shell 61, and the front side of the column abutment 47 is used to abut the left and right ends of the shell 61, so that the top platform 31 will not move when driving the shell 61 to tilt backward, and the column abutment 47 mainly plays a limiting role, rather than a clamping role;

[0030] Simply place the counterweight at the opening of the housing 61 without pushing it deep. When the housing 61 tilts back, the counterweight will automatically slide into the housing 61. Therefore, the placement of the counterweight only needs to consider the left and right directions.

[0031] The top platform 31 is provided with an opening, and a guide roller 32 located in the opening is rotatably connected to the top platform 31, the axis of the guide roller 32 is parallel to the axis of the shaft Ⅰ14, the guide roller 32 is tangent to the upper end surface of the top platform 31, and the surface of the guide roller 32 is provided with a flexible surface 33 of rubber material for anti-slip, the flexible surface 33;

[0032] When suspending the housing 61, it is not necessary to place it precisely. The housing 61 can be roughly placed on the four top platforms 31. At this time, the top platforms 31 on the left and right sides are brought close to each other so that the column stoppers 47 are close to the housing 61 for limiting, thereby reducing the difficulty of suspension.

[0033] Further, a shaft III 41 is rotatably connected to a corner of the top platform 31 away from other top platforms 31, a ring 42 is fixedly connected to the shaft III 41, a hole II is provided on the ring 42, a pin 43 is provided in the gap of the hole II, the head of the pin 43 is located on the upper side to prevent the pin 43 from slipping out of the hole II, a plurality of holes I 36 distributed around the shaft III 41 are provided on the top platform 31, the pin 43 can be inserted into any one of the holes I 36, the upper end of the shaft III 41 is fixedly connected to a base I 44, a telescopic cylinder II 45 is installed on the upper end of the base I 44, the movable end of the telescopic cylinder II 45 is arranged horizontally, and a There is a fixed base II 46, and a column-belt abutment 47 is fixed to the front and rear sides of the base II 46 respectively, so that the two column-belt abutments 47 on a top platform 31 are pressed against the two wall surfaces of the outer shell 61 to increase stability. The telescopic cylinder II 45 is used to independently and accurately adjust the position of the column-belt abutment 47, which can further reduce the difficulty of suspension. The fine docking with the outer shell 61 is adjusted by the present application itself without manual or other suspension equipment. Preferably, the column-belt abutment 47 is detachably fixed to the base II 46 to reserve column-belt abutments 47 of different specifications or column-belt abutments 47 of different spacings.

[0034] Furthermore, the wheel 23 that runs on the bottom frame 11 is rotatably connected at the lower end of the middle frame 21, and the wheel II35 that runs on the middle frame 21 is rotatably connected at the lower end of the top platform 31, so as to increase the stability of the position adjustment.

[0035] Further, such as Figure 7 As shown, a support is installed at the lower end of the base frame 11 to share the weight and reduce the pressure on the structure below the base frame 11. The support includes a bottom support member Ⅰ51 and a support member Ⅱ52 fixedly connected to the upper end of the support member Ⅰ51. The support member Ⅱ52 is a bridge-like structure with a horizontal truncated cone at the upper part and a structure at the lower part to increase the distance from the support member Ⅰ51. The upper end of the support member Ⅱ52 is longitudinally slidably connected to two pressure-dividing rods 53. The lower end of the pressure-dividing rod 53 is fixedly connected to a limiting portion. The upper end of the pressure-dividing rod 53 is fixedly connected to a connecting seat 54. When only one support is used, the connecting seat 54 is fixedly connected to the lower end center of the base frame 11. A compression spring is sleeved on the pressure-dividing rod 53. The two ends of the compression spring are respectively abutted between the support member Ⅱ52 and the support member Ⅰ51, and the limiting portion abuts against the lower end of the horizontal truncated cone.
