[0020] Example: Figure 1-5As shown, the utility model provides a construction ladder for road and bridge construction, including a fixed seat 1, a base frame 2 is fixedly installed on the top surface of the fixed seat 1, a splicing frame 3 is fixedly installed on the top surface of the base frame 2, the base frame 2 and the splicing frame 3 both include an upper fixed frame 4, a lower fixed frame 41 and a support rod 42, the number of the support rod 42 is four and is fixed to the four corners between the upper fixed frame 4 and the lower fixed frame 41 by bolts, both sides of the fixed seat 1 are symmetrically installed with stabilizing devices 5, the number of the stabilizing devices 5 is four, the stabilizing devices 5 include a mounting member 51, the mounting member 51 is slidably installed in one side of the fixed seat 1, and a rotating member 52 is fixedly installed on one side of the mounting member 51. A support plate 53 is fixedly installed on one side of 52, and the support plate 53 is rotatably installed on one side of the mounting member 51 through the rotating member 52. A ground nail 54 is inserted into one end of the support plate 53. The fixing seat 1 is symmetrically installed with positioning components 11 on both sides of the stabilizing device 5. The positioning component 11 includes a limit pin 111, a sliding member 112 is fixedly installed on one end of the limit pin 111, and a return spring 113 is fixedly installed on one end of the sliding member 112. A positioning buckle 55 is fixedly installed in the middle of one side of the mounting member 51. The limit pin 111 is slidably inserted in the positioning buckle 55 through the sliding member 112 and the return spring 113, and the positioning component 11 and the positioning buckle 55 cooperate with each other.

[0021] When it is necessary to install the construction frame, the fixing base 1 of the construction frame is fixed on the concrete foundation by bolts. After the fixing is completed, the four stabilizing devices 5 are respectively installed in the two installation grooves 12 through the installation parts 51, and two stabilizing devices 5 are installed in each installation groove 12. The stabilizing device 5 is limited by the positioning assembly 11 and the positioning buckle 55. After the limiting is completed, with the cooperation of the rotating member 52, the support plate 53 is rotated so that one end of the bottom surface of the support plate 53 is in contact with the ground. After the contact, the support plate 53 is limited and fixed by the ground nails 54. Through the cooperation of the four groups of stabilizing devices 5 and the positioning assembly 11, the stability of the fixing base 1 is increased after completion, and the stability of the construction ladder after assembly is increased. This solves the problem that the existing road and bridge construction ladder is installed and fixed only by the concrete foundation and bolts to complete the installation and fixing of the base of the road and bridge construction ladder, resulting in poor stability of the construction ladder and prone to safety hazards.

[0022] Both sides of the upper fixing frame 4 and the lower fixing frame 41 that fit together on the base frame 2 and the splicing frame 3 are sleeved with a splicing fixing assembly 6, and the splicing fixing assembly 6 includes a splicing plate 61, and four corners of one side of the splicing plate 61 are fixedly installed with a clamping block 62, and the number of the clamping blocks 62 is four, and the four clamping blocks 62 are respectively clamped in the base frame 2 and the splicing frame 3, and the middle of both sides of the splicing plate 61 are fixedly installed with a fixing buckle 63, and the two fixing buckles 63 are threadedly clamped with a threaded buckle 64, and the two threaded buckles 64 penetrate the fixing buckle 63 and are respectively threadedly clamped in the base frame 2 and the splicing frame 3;

[0023] After the splicing frame 3 is fixed to the base frame 2 by bolts, with the cooperation of the clamping blocks 62 in the two splicing fixing components 6, the two splicing fixing components 6 are respectively installed on the two side surfaces of the upper fixing frame 4 and the lower fixing frame 41 that are in contact with the base frame 2 and the splicing frame 3, and fixed by the fixing buckles 63 and the threaded buckles 64. The splicing and fixing between each two adjacent layers of the frames are completed by the splicing fixing components 6, thereby increasing the overall stability of the construction ladder after installation. Similarly, the splicing installation of the two splicing frames 3 also increases its stability after splicing through the two splicing fixing components 6.

[0024] The base frame 2 and the splicing frame 3 are fixedly mounted with a positioning sleeve 421 at one end of the surface of one side of the two upper and lower adjacent support rods 42 of the base frame 2 and the splicing frame 3, and a positioning pin 422 is inserted in the two positioning sleeves 421, and the positioning pin 422 cooperates with the positioning sleeve 421. The positioning sleeves 421 respectively installed at one end of the surface of one side of the two upper and lower adjacent support rods 42 of the base frame 2 and the splicing frame 3 cooperate with the corresponding positioning pin 422 to complete the connection and fixation of the base frame 2 and the splicing frame 3 (the two positioning sleeves 421 installed at one end of the surface of one side of the two upper and lower adjacent support rods 42 are a group with a positioning pin 422, and the connection between each two adjacent layers of the frames is connected through four groups), which increases the stability of the base frame 2 and the splicing frame 3 after splicing. Similarly, the splicing installation of the two splicing frames 3 also increases their stability after splicing through the positioning sleeves 421 and the positioning pin 422.

[0025] Both sides of the fixing seat 1 are provided with installation grooves 12, and the installation parts 51 are slidably installed in the installation grooves 12. The installation limit of the four stabilizing devices 5 is completed by cooperating with the two installation grooves 12 and the installation parts 51.

[0026] A guide bar 511 is fixedly installed on the bottom surface of the mounting member 51, and a guide groove 13 is opened on the bottom surface of the mounting groove 12. The guide bar 511 is slidably clamped in the guide groove 13. The guide bar 511 is used to limit the mounting member 51 on both sides of the fixing seat 1, and assists the mounting member 51 to slide in the mounting groove 12, thereby increasing the stability of the mounting member 51 after installation.

[0027] Ladders 43 are installed in both the base frame 2 and the splicing frame 3. The ladders 43 cooperate with the base frame 2 and the splicing frame 3. The ladders 43 installed in the base frame 2 and the splicing frame 3 help construction workers go up and down in the construction ladder.

[0028] Protective nets 44 are fixedly installed on the four sides of the base frame 2 and the splicing frame 3. A door opening 45 is opened in the edge of the protective net 44 on one side of the base frame 2 and the splicing frame 3. The four sides of the base frame 2 and the splicing frame 3 are protected by the protective net 44. The protective door is installed and fixed through the door opening 45 opened in the protective net 44 on one side of the base frame 2 and the splicing frame 3, which is convenient for construction personnel to enter the base frame 2 and the splicing frame 3.

[0029] Working principle: when the construction frame needs to be installed, the fixing base 1 of the construction frame is fixed on the concrete foundation by bolts. After the fixing is completed, the four stabilizing devices 5 are respectively installed in the two installation grooves 12 through the installation parts 51. Two stabilizing devices 5 are installed in each installation groove 12. The stabilizing devices 5 are limited by the positioning assembly 11 in cooperation with the positioning buckle 55. After the limiting is completed, the support plate 53 is rotated with the cooperation of the rotating member 52 so that one end of the bottom surface of the support plate 53 is in contact with the ground. After the contact, the support plate 53 is fixed by the ground nails 54. The stability of the fixing base 1 after completion is increased by the cooperation of the four groups of stabilizing devices 5 and the positioning assembly 11.

[0030] After the splicing frame 3 is fixed to the base frame 2 by bolts, with the cooperation of the clamping blocks 62 in the two splicing fixing components 6, the two splicing fixing components 6 are respectively installed on the two side surfaces of the upper fixing frame 4 and the lower fixing frame 41 that are in contact with the base frame 2 and the splicing frame 3, and fixed by the fixing buckles 63 and the threaded buckles 64. The splicing and fixing between each two adjacent layers of the frames are completed by the splicing and fixing components 6. Similarly, the splicing and fixing of the two splicing frames 3 are also completed by the two splicing and fixing components 6.
